DreymaR's Big Bag of Keyboard Tricks

For Linux using XKB

• New "Colemak[eD]" AltGr mappings (lv3-4) putting dead keys on AltGr+symbol keys and reworking most other mappings
• Angle/Wide ergo modifications to improve wrist angles, hand spacing and right pinky stretch/load effort
• Curl(DH) ergo modifications to encourage natural finger curvature
• An "Extend" layer using Caps Lock as a modifier (lv5-8) for navigation/editing from the home position and more
• For several locales, a 'Unified Symbols' layout with only a few necessary changes from the standard Colemak[eD]; Also, a layout to 'Keep Local Symbols' like their default (QWERTY-type) counterparts for that locale
• Intuitive phonetic layouts for Cyrillic, Greek and Hebrew scripts
• Mirrored Colemak that allows one-handed typing (if I ever break an arm...)
• The 4 Tarmak transitional Colemak layouts for learning Colemak(-DH) in smaller steps if desired

More info

Run the install and setxkb scripts with -h (or look inside them) for more help and info about their workings!

Learn about setxkb.sh "model locale variant" shortstring syntax in the BigBag. The default is "5cw us us": PC105(ISO) board with Curl(DH)AngleWide mods, US locale, Cmk-eD UniversalSymbols variant. To switch to, say, an ANSI board without ergo mods, that's 4n instead of 5cw. Look in the scripts.

NOTE: It may be necessary to select "Use system defaults" if you have changed anything in the OS GUI layout settings.

These files are updated to XKB-data v2.23.1-1ubuntu1, 2018. The xkb-data package is consistent enough between distros. I use the Debian xkb-data, sometimes with some Ubuntu updates. The .deb packages may be opened using dpkg -x or ar -xv (from binutils) on Linux, and for instance PeaZip on Windows.

TODO:

• Is there a way to clear the LevelFive mod on all the Extend mappings by default? Or must I be more careful with each RedirectKey()?
  • Example: Q -> Esc -> Caps caused people trouble, as Ext+Q would act as Esc+Caps.
  • Possibly, finally make a new key type EIGHT_LEVEL_EXTEND with the action clearmods=LevelFive added to state 5-8? No, no actions.
  • In xkb/types/level5 under EIGHT_LEVEL_SEMIALPHABETIC I used preserve[Shift] = Shift;. We need the opposite here, to discard lvl5.
  • See for instance https://www.x.org/releases/X11R7.5/doc/input/XKB-Enhancing.html
  • "Usually, all modifiers introduced in 'modifiers=' list are used for shift level calculation and then discarded."
  • Does this mean that LevelFive should've been discarded but isn't? Is it an XKB bug?
• From Daniele at the Cmk Discord: Try out localectl?
  • E.g., 'localectl set-x11-keymap us pc105aw-sl cmk_ed_dh lv5:caps_switch_lock,misc:extend' should work to make changes persistent?
• The Curl(DH) model implementation has to go as it may mess w/ QWERTY. Instead, I should use two Extend variants.
  • It also seems very hard for some newcomers to understand. So yes, I should have the Angle mod only and not CurlAngle models.
  • Also, matrix users want the V-D swap without an Angle mod! Another nail in the coffin for the Curl models.
  • Actually, should I make a NoModel CurlAngle layout for the model impaired? Vanilla, Curl(DH) and Curl(DH)Angle then.
  • Could just make a CurlAngle option!
  • But first, just the Curl with D-V swap built in. Just let the Extend Paste function be where it falls for now.
• Update to the latest xkb-data: https://ubuntu.pkgs.org/20.04/ubuntu-main-amd64/xkb-data_2.29-2_all.deb.html
• Find out how to change the rules component properly to allow compiling and eventually merging to the main repo?
• Migrate from ~/.bashrc to ~/.xprofile? The latter is more appropriate, but which setups source it and which ones don't?
• Could use an key code alias defined in keycodes/evdev (alias = ), instead of the code?
• Test this method for using a local dir, by Bjørnar "zkf" Hansen:
  • Copy the xkb-data_mod/xkb dir to, say, /usr/local/bigbag/xkb and setenv MYXKB <dir> (setenv not necessary, just for here)
  • setxkbmap <parameters> -print | xkbcomp -I -I$MYXKB -I/usr/share/X11/xkb - $DISPLAY
  • See https://github.com/DreymaR/BigBagKbdTrixXKB/issues/14
  • More useful info in this comment: https://github.com/DreymaR/BigBagKbdTrixXKB/issues/14#issuecomment-767590722
  • "-I/usr/local/share/X11/xkb can be written more succinctly as -I. if you first cd into this directory."
• An earlier comment on the local dir subject, by [email protected]:

  • https://unix.stackexchange.com/questions/397716/custom-keyboard-layout-without-root
  • `setxkbmap -I $MYXKB -print | xkbcomp -I $MYXKB - "$DISPLAY"
  • "I made that tweak to setxkb and some small changes to use a hardcoded $HOME dir path, and it appears good."
• For an EsAlt variant as in EPKL:

    key <AE04> { [             4,        dollar,       dead_currency,            EuroSign ] }; // 4
    key <AD07> { [             l,             L,               U2039,       guillemotleft ] }; // QWE U Cmk L
    key <AD08> { [             u,             U,                   ú,                   Ú ] }; // QWE I Cmk U - EsAlt
    key <AC01> { [             a,             A,                   á,                   Á ] }; // QWE A Cmk A - EsAlt
    key <AC06> { [             h,             H,           leftarrow,          rightarrow ] }; // QWE H Cmk H
//    key <AC07> { [             n,             N,                   ñ,                   Ñ ] }; // QWE J Cmk N - EsAlt ANSI
    key <AC08> { [             e,             E,                   é,                   É ] }; // QWE K Cmk E - EsAlt
    key <AC09> { [             i,             I,                   í,                   Í ] }; // QWE L Cmk I - EsAlt
    key <AC10> { [             o,             O,                   ó,                   Ó ] }; // QWE ; Cmk O - EsAlt
    key <LSGT> { [             ñ,             Ñ,                  oe,                  OE ] }; // <>          - EsAlt ISO
//    key <AB06> { [             k,             K,              endash,             uparrow ] }; // QWE N Cmk K - ANSI
    key <AD11> { [   bracketleft,     braceleft,           masculine,         ordfeminine ] }; // [{

DONE:

• 2020-11-05: Switched to the new DH = DHm standard (was DH = DHk)
• Changed the default layout for the setxkb.sh script to US (UniSym): In my experience, most users that struggle with the setup want US English.
• To get back to your old layout/model, use setxkb 4n/5n [loc]. You may also specify mod loc [var]; omit var for the default (basic) variant.
• Separated out the F# key block in the extend file: People complain that their TTY shortcuts aren't working because of it. Ext+AltGr+F# works though.
• Relieve the sudo requirement. And add an option to change the X11 dir since Nix uses another place. Pulled from [email protected]
