-* cbbrowne custom keyboard
-
- Due to cbbrowne@acm.org
- Christopher Browne
-
- This was originally based on the default keyboard map, but I have
- been doing sundry experimentation:
-
-** Useful Experiments
-
- - It made sense to mess around some with keyboard maps.
- - I added a keypad, originally based on keymaps/numpad.c, but
- mighty substantially revised, as that one seems to be rotated 90
- degrees from usual conventions for number pads
- - The keypad layer also includes some sample "hacks" of cool things,
- all using actions attached in using the function action_get_macro()
- - Key [1][2] aka "q" types out my name, cbbrowne, as a fun example
- of a key generating a bunch of keystrokes. The keystroke is
- sufficiently inconvenient that it isn't terribly practical for me
- to use it, but hey, it shows how others might use this facility
- in a more useful context.
- - Key [2][2] aka "a" uses a random number generator to select a digit 0-9 at random
- - Key [3][2] aka "z" uses a random number generator to select a letter a-z at random
- - Key [1][3] aka "e" spits out the keymap version number
- - Trying out sgoodwin's "hold Enter down to get Shift"
- - Liking this Quite Well Enough...
- - Applied this to both Shift and Quote
- - It seems likely that Alt should get a right-hand-side, akin to this...
- - Alt needs to move, and get a RHS
- - Hence ALTRIGHT, and shifted ROT_LED over
- - Emacs likes this!!! :-)
- - I'm suspicious that I'll want to shift ROT_LED another location over,
- so some modifier can replace the OS/KC_LGUI key
- - I have added an alternate ADJUST layer that is activated via update_tri_layer()
- - e.g. - LOWER+RAISE simultaneously
- - This seems entirely more useful for handling my "special keys"
- like the random numbers, user name, and such, than the keypad layer
- - The _ADJUST layer provides a good place to have RESET
- - But this isn't strictly enough; I want RESET somewhat accessible from
- main layer lest an error hide that layer
- - I never use the OS/KC_LGUI key (that's Command on MacOS, Windows
- Key on Windows), so that's a good place to have it as a chord of
- some sort
-
-
-** Some code structure ideas
-
- Each layer is given a name to aid in readability, which is then
- used in the keymap matrix below. The underscores do not denote
- anything - you can have a layer called STUFF or any other name.
-
- Layer names don't all need to be of the same length, obviously, and
- you could also skip them entirely and just use numbers, though that
- means needing to manage the numbers.
-
- It is preferable to keep the symbols short so that a line worth of
- key mappings fits compactly onto a line of code. It might be an
- interesting idea to express the maps rotated 90%, so that you
- only need to fit 4 symbols onto each line, rather than 12.
-
- I use enums to manage layer IDs and macro IDs so that I don't need
- to care (beyond "start at 0", and arguably even that's not needed)
- about their values.
-
-** Things I did not like about the default mapping
-
-
- - I found control too hard to get to. I use it more than Tab, so
- switched it there.
- - Having dash on [lower-j] is a bit nonintuitive, but may be OK
- - I switched ESC/TAB/M(0) around
- - I'm suspicious that I want to shift M(0) from [4][1] to [4][2],
- and shift ESC off the first column so KC_LCTL and KC_LALT can
- be on the first column.
- - I needed to swap ' and ENTER
-
-** Unuseful experiments
-
-I have tried some things out that didn't turn out particularly well.
-I'll note some of these for posterity, hopefully helpful in not doing
-unwise things again...
-
- - I tried added Workman alongside Dvorak and Colemak
- - Boy, oh boy, these don't help!!!
- - I have done 30 years of learning of Emacs key mappings, and
- these alternative keyboards massively mess me up
-
- - Space Cadet Shift; switching L_SHIFT to KC_LSP0, so that when I
- just hit SHIFT, I get a left parens. In principle, this is great
- for Lisping.
- - Unfortunately, there are times when mouse interfaces use SHIFT
- to allow selecting multiple items, and this really interferes
- with that
-
-** TODO
-
- - I use tmux quite a lot; the mollat keymap seems to have some
- interesting helpers. It might be interesting to add a "tmux
- layer," or to have a few keys in a layer oriented towards that
- - Keys for...
- - Picking windows 0 thru 8
- - next/prev/new window
- - The mollat tmux layer also suggests some thoughts about Emacs
- helpers.
- - I do not presently have anything that handles X11 screen
- switching, as with Control-Alt-various
- - I ought to probably look into KC_LEAD, to have some key combos
- that do not need to be concurrent
- - The jeebak keymap seems to have some neat ideas:
- - Number layer which is aggressive about having numbers in several places
- - TouchCursor layer seems interesting
- - It sets up a layer with cursor keys on the home keys
- - The jeremy-dev keymap has some very interesting concepts
- - Shift hands outwards; the special keys go in the center
- - Symbol layer has some compound keys for C operators like /=, *=, -=, +=, ...
- - This is likely what I'll use for my XD75re, and maybe I'll fork a
- planck keymap for similar
