# callum’s planck layout
|
||||
|
||||
This is a layout for the grid planck, built with a few ideals in mind:
|
||||
|
||||
- Consistent and minimal response times should be maintained. Keys that react
|
||||
differently depending on whether they are tapped or held, keys that react
|
||||
differently if they are double tapped, etc. should be avoided – they
|
||||
inevitably send their keycode later than a normal key – interrupting the
|
||||
immediate feedback from the screen. Therefore we restrict ourselves to
|
||||
chording as our only means of getting more than one symbol out of a single
|
||||
physical key.
|
||||
|
||||
- The hands should never need to leave the home position. The usual culprit for
|
||||
this is the arrow cluster, so the arrow cluster should be as close to home as
|
||||
possible.
|
||||
|
||||
- There should be two of every modifier (one on each side), otherwise certain
|
||||
long key combinations become hard to make.
|
||||
|
||||
- It should be possible to do things you might want to do while using the mouse
|
||||
with only the left hand (e.g. change tabs, navigate back or forwards in
|
||||
browser history).
|
||||
|
||||
- Symbols should be arranged so that the most frequently used are easiest to
|
||||
reach. This includes numbers, and lower numbers are more commonly used than
|
||||
higher ones. (number arrangement borrowed from [dustypomeleau’s minidox
|
||||
layout][]).

|
|||
A keymap for 34 keys with 4 layers and no mod-tap.
|
||||
|
||||
|
||||
|
||||
## Details
|
||||
|
||||
- Hold `sym` to activate the symbols layer.
|
||||
- Hold `nav` to activate the navigation layer.
|
||||
- Hold `sym` and `nav` together to activate the numbers layer.
|
||||
- The home row modifiers are oneshot so that it's possible to modify the
|
||||
keys on the base layer, where there are no dedicated modifiers.
|
||||
- `swap win` sends `cmd-tab` for changing focus in macOS but holds `cmd`
|
||||
between consecutive presses.
|
||||
- `swap lang` behaves similarly but sends `ctrl-space`, for changing input
|
||||
language in macOS.
|
||||
|
||||
## Oneshot modifiers
|
||||
|
||||
The home row modifiers can either be held and used as normal, or if no other
|
||||
keys are pressed while a modifier is down, the modifier will be queued and
|
||||
applied to the next non-modifier keypress. For example to type `shift-cmd-t`,
|
||||
type `sym-o-n` (or `nav-a-t`), release, then hit `t`.
|
||||
|
||||
You can and should hit chords as fast as you like because there are no timers
|
||||
involved.
|
||||
|
||||
Cancel unused modifiers by tapping `nav` or `sym`.
|
||||
|
||||
### Userspace oneshot implementation
|
||||
|
||||
For my usage patterns I was hitting stuck modifiers frequently with [`OSM`][]
|
||||
(maybe related to [#3963][]?). I'd like to try to help fix this in QMK proper,
|
||||
but implementing oneshot mods in userspace first was:
|
||||
|
||||
1. Fun.
|
||||
2. A good exploration of how I think oneshot mods should work without timers.
|
||||
|
||||
So in the meantime, this [userspace oneshot implementation][] is working well
|
||||
for me.
|
||||
|
||||
## Swapper
|
||||
|
||||
`swap win` sends `cmd-tab`, but holds `cmd` between consecutive keypresses.
|
||||
`cmd` is released when some other key is hit or released. For example
|
||||
|
||||
nav down, swap win, swap win, nav up -> cmd down, tab, tab, cmd up
|
||||
nav down, swap win, enter -> cmd down, tab, cmd up, enter
|
||||
|
||||
`swap lang` sends `ctrl-space` to swap input languages in macOS and behaves
|
||||
similarly.
|
||||
|
||||
[Swapper implementation.][]
|
||||
|
||||
## Why no mod-tap?
|
||||
|
||||
[Mod-tap][] seems to be by far the most popular tool among users of tiny
|
||||
keyboards to answer the question of where to put the modifiers, and in the
|
||||
right hands it can clearly work brilliantly, but I've always found myself error
|
||||
prone and inconsistent with it.
|
||||
|
||||
With dedicated modifiers, there are three ways one might type `ctrl-c`:
|
||||
|
||||
ctrl down, ctrl up, c down, c up
|
||||
ctrl down, c down, ctrl up, c up
|
||||
ctrl down, c down, c up, ctrl up
|
||||
|
||||
Basically, you never have to worry about the keyups, as long as the keydowns
|
||||
occur in the correct order. Similarly, there are three ways one might type
|
||||
`ac`:
|
||||
|
||||
a down, a up, c down, c up
|
||||
a down, c down, a up, c up
|
||||
a down, c down, c up, a up
|
||||
|
||||
Replace `a` with `ctrl` and this is exactly what we had before! So if we want
|
||||
to put `a` and `ctrl` on the same key we have a problem, because without
|
||||
considering timing these sequences become ambiguous. So let's consider timing.
|
||||
|
||||
The solution to the ambiguity that QMK employs is to configure the
|
||||
`TAPPING_TERM` and consider a key held rather than tapped if it is held for
|
||||
long enough. My problem with this is that it forces you to slow down to use
|
||||
modifiers. By its very nature the tapping term must be longer than the longest
|
||||
you would ever hold a key while typing on the slowest laziest Sunday afternoon.
|
||||
I'm not typing at 100% speed at all times, but when I am, having to think about
|
||||
timing and consciously slow down for certain actions never fails to trip me up.
|
||||
|
||||
So alas, mod-tap is not for me -- but if it works for you, more power to you.
|
||||
:)
