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