 | |

|    Layer names don't all need to be of the same length, obviously, and

 | |
| 
 | |
|    - 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!

 | |

|    - Need to think about what zsh and readline actions I use lots

 | |
|    - How about Alt-F1 thru Alt-F8?
 | |
|    - What's the keystroke to get from X to console these days?
