! A buttonboard layout with one button per letter ! of the English (U.S.) alphabet, and four symbols ! per button. Two layout buttons, "left" and "top", ! provide access to all four layouts of the presumed ! 2x2 matrix (Diagram for typing symbols). ! ! Spacing and deleting is handled by the left thumb ! (Diagram for spacing and deleting). ! ! Movement and placement is handled by the right thumb ! (Diagram for placing content). ! Ideally, there would be one button per layout ! for activating each rather than temporarily switching. !
! For a Raspberry Pi buttonboard. ! Model No.: RPI-KYB ! 78 buttons ! ! Very odd physical design, and peculiar failureswhen ! holding multiple buttons. ! ! The modifier buttons are wide enough for thumbs, as if ! the hands were meant to be crossed, wrist on top of wrist. ! Perhaps so, then the palm could press that extra wide ! barbutton. ! ! It has movement buttons for left/up/down/right ! sort of convenient for the thumb, with wrists crossed. !---------------------------------------------------------. !esc|F1 F2 F3 F4 F5 F6 F7 F8 F9 F10|num prt fdel| ! |F11 F12 scr| srq ins| !---^----------------------------------------^------------| ! ` 1 2 3 4 5 6 7 8 9 0 - = | bdel| !---------------------------------------------------^-----| !tab | q w e r t y u i o p [ ] \ | !-----^---------------------------------------------------| !caps | a s d f g h j k l ; ' | enter| !------^-------------------------------------------^------| !shift | z x c v b n m , . / | shift| !--------^---------------------------------------^--------| !ctl|fn |spr|alt | barbutton |altg|ctl| | up| | ! | | | | | | |---+---+---| ! | | | | | | |lft|dwn|rt | !---^---^---^----^-------------------^----^---^---^---^---' !

! On rare occassion, a button press will continuosly repeat itself, ! as if it were still held. When typing, this appears as a single ! letter continuously typed. ! ! The only way to stop it seems to be to randomly type as many ! buttons as possible until the something else (from one of those ! randomly typed buttons) appears on the screen. Then, delete ! the mess. ! [...prior failures when used with the X Window System...] ! The PrtScn button (keycode 107) seems incompatible ! with Shift Lock in the X Window System, at least ! when using xmodmap to set the buttonboard map. ! ! In other words, the character mapped to ! PrtScn (keycode 107) for Shift ! fails to be produced with Shift Lock. ! (Currently untested with Shift.) ! ! For example, with the following mapping: ! keycode 107 = g 3 G asterisk ! The "3" will be unattainable with Shift Lock. ! The PrtScn button (keycode 107) is slightly incompatible ! with Mode switch of the X Window System. ! ! A character mapped to the PrtScn button ! for the "Mode switch" is produced only after ! the Mode switch button has been released. ! ! In other words, hold the Mode switch button then ! type the PrtScn button, but nothing appears ! to happen. Release the Mode switch button and ! the character is produced. ! ! Typing anything else before releasing Mode switch ! will prevent whatever character was mapped ! to the PrtScn button from appearing. !
! Four fingers means four buttons in a row. ! One row above and one row below means three rows. ! Twelve buttons per hand means 24 buttons total. ! ! There are usually 47 buttons with symbols, ! two per button. Two "shift" buttons for ! the other half, but only one needed. ! ! As that is almost twice as many as 24, four symbols ! per button encompasses all. Two "shift" buttons ! can suffice for three additional layouts by holding ! both for the third. ! Consider having four symbols per button in a ! 2 by 2 matrix, the one at left-bottom as default. ! ! left-top top ! left default ! ! The layout buttons, t.i. "shift" buttons, ! are "left" for the symbol left of the default, ! "top" for the symbol above the default, ! and both for the left-top symbol. !
! Letters are listed in familiar alphabetical order
! from left to right and then top to bottom,
! the same as when writing and reading. Add two more
! buttons outside the forefingers for "y" and "z".
! Small letters are the default layout and their
! capitals are a separate layout as usual
! (and left of the small letters as expected).
!
! Numbers are sequential as when counting,
! and familiarly arranged as on phones and ATMs.
! The ten digits are grouped within the twelve buttons
! of the right half, with the minus, plus, and period.

! Before applying a keymap, consider creating an alias to a ! command that restores the current keymap (default or custom) by ! typing a single letter. Then make sure to know where that ! single letter is mapped on the new keymap, and where the Return ! key is mapped, too. ! The suffix for a keymap doc is typically of no consequence. ! A buttonmap sometimes can be compressed. ! Assuming this file is named "loadkeys--compact--rpi-kyb.htm", try: ! sudo \ ! loadkeys \ ! --clearstrings \ ! --clearcompose \ ! loadkeys--compact--rpi-kyb.htm \ ! > results 2>&1 ! ! That sends any output and errors to the "results" document. ! A successful load usually has no results, otherwise review the ! output and errors for what happened unexpectedly. ! Use "sudo loadkeys --default" for restoring the default keymap ! unless "defkeymap.map" is non-existent. Or reboot to restore. ! See manual for "keymaps" and "showkey", too. ! Use "loadkeys -b" with a keymap in order to produce a binary ! suitable for busybox. Note busybox has "loadkmap" instead. ! Use "dumpkeys -l" for information about support by the system. ! Information last obtained: ! Keycode range supported by kernel: 1 - 255 ! Max number of actions bindable to a key: 256 ! Number of keymaps in actual use: 128 ! of which 121 dynamically allocated ! Ranges of action codes supported by kernel: [blank] ! Number of function keys supported by kernel: 256 ! Max number of compose definitions: 256 ! number of compose definitions in actual use: 68 ! ! Also lists symbols recognized. Notably, F246 was highest ! function key symbol. There were ten other possibilities: ! Find, Insert, Remove, Select, Prior, ! Next, Macro, Help, Do, Pause. ! Within the console the Control modifier is effective with only ! the ASCII values 1-31, known by the values: a-z, and [ \ ] ^ _ ! So, there is "Control_a" but no "Control_A". Null is "nul". ! ! Contrarily, the Meta modifier modifies the ASCII values 0-127, ! therefore both "Meta_a" and "Meta_A" are available. ! ! Together, there is "Meta_Control_a" but no "Meta_Control_A", ! because no "Control_A". ! There are usually 256 possible combinations of 9 modifier keys ! in addition to the unmodified key (plain). Thereby, 257 total ! and all on the same line. ! ! Setting only the unmodified key (column 0) automatically sets ! all the modified combinations to that value, too, which is a ! requirement for assigning a modifier to a keycode. ! ! For example: ! keycode 29 = Control ! is the same as repeating the name "Control" 256 more times for ! the other 256 columns on the line. ! The first value (column 0) is for the unmodified key, the ! second value (column 1) is when modified by shift, and so on. ! plain 0 ! shift 1 altgr 2 control 4 alt 8 ! shiftl 16 shiftr 32 ! ctrll 64 ctrlr 128 ! capsshift 256 ! Or instead, each desired combination for a keycode can be set ! individually by listing modifier names prior to the keycode, ! one combination per line. ! [ need to test this again, seems contrary to loadkeys manual ] ! ! A plus sign + before the value means the shifted value will be ! returned when caps lock is active. ! For example, it is quite common to need to type a variable ! named with multiple words separated by underscores while using ! all uppercase letters. That is automatic with shift lock ! which allows typing all the shifted values. Caps lock usually ! allows typing the shifted values of only a to z, then requires ! using shift for other keys as needed. Alternatively, allow ! typing an underscore with capslock without having to use the ! shift key for underscore (from the minus key). Presuming the ! keycode is 12 for the key: ! keycode 12 = +minus underscore ! ! Additionally, a plus sign before the shifted value means the ! plain value is returned when using both caps lock and shift: ! keycode 16 = q +Q ! Oddly, it seems a-z need the plus sign for caps lock, too, so: ! keycode 16 = +q +Q ! Text can be set for any key rather than only one character. ! Such texts are usually associated with the function keys ! F30-F246 (typically unavailable on keyboards). For example: ! commands for the command interpreter or for emacs; a common ! phrase or statement; some other console code. After defining ! text for a symkey, associate that symkey with a keycode for a ! button. Type that button once to produce the whole text for ! whatever program currently has focus. ! ! string F30="\030r" ! Control x (octal value) and r for emacs ! keycode 58=F30 ! 58 is the caps lock button ! ! string F31="\160\141\163\163\167\157\162\144" ! password ! keycode 183=F31 ! 183 is the F13 key ! ! string F32="\012" ! newline and HTML paragraph mark ! shift keycode 28=F32 ! Return button with shift modifier ! ! Actual control characters are also okay, as typed with the ! command `quoted-insert' (C-q) in emacs. !
