/* 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. */
/* This was originally based on planck/keymaps/default/default.c, and
then cbbrowne has revised things */
/* 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'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 needed to swap ' and ENTER
- All of the above are done :-)
- Dropped out support for Dvorak and friends. They aren't
improvements to me
*/
/* Some interesting things implemented
- There is a macro that writes out "cbbrowne" to show that 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
- I do indeed want a sweet number pad!
*/
/* Other things to do...
- Need to think about what zsh and readline actions I use lots
- 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?
- A layer for doing console switching would not be a bad idea
- I haven't got page-up/page-down, let's have that...
