/* 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. */

/* Things I did not like about the default mapping
|
|
|
|
- I find control too hard to get to. I think I'll want it on a
|
|
left finger. Gonna need to lose something to do that...
|
|
- Almost certainly, KC_LCTL should be on [2][1]
|
|
- having dash on [lower-j] is a bit nonintuitive, but may be OK
|
|
- I'll bet I should switch ESC/TAB
|
|
- 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 think I wanna swap ' and ENTER
|
|
|
|
- All of the above are done :-)
|
|
|
|
- I'm keeping Colemak and Dvorak around for reference, and added
|
|
Workman just for fun. They're useless to me, though.

/* Some interesting things implemented
|
|
|
|
- There is a macro that writes out "cbbrowne" just because I could
|
|
- There is a (somewhat cruddy) linear congruential random number
|
|
generator.
|
|
- I would like to be seeding it with clock info to make it look
|
|
more random
|
|
- There are two macros that use the random number generators
|
|
- one, M_RANDDIGIT, generates a random digit based on state
|
|
of the random number generator
|
|
- the other, M_RANDLETTER, generates a random letter based on state
|
|
of the random number generator
|
|
- in both, note the use of register_code()/unregister_code()
|
|
to indicate the desired key
|
|
*/
|
|
|
|
/* Other things to do...
|
|
|
|
- Need to think about what zsh and readline actions I use lots
|
|
- Wanna figure out macros, so I can put in a "cbbrowne" macro
|
|
- Ought to ensure that Control-Alt-Delete is convenient enough
|
|
- How about Alt-F1 thru Alt-F8?
|
|
- What's the keystroke to get from X to console these days?
|
|
- I do indeed want a sweet number pad!
|
|
- A layer for doing console switching would not be a bad idea
