This was originally based on the default keyboard map, but I have been
|
|
doing sundry experimentation:
|
|
|
|
1. 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
|
|
|
|
|
|
2. 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 used 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.
|
|
|
|
3. 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
|
|
|
|
4. 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
|
|
|
|
5. 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
|
|
* 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
|
|
- Touch layer seems interesting
