it didn’t take long.

BEAKL Vi’s placement of the Enter key and it’s improvement to chords and sequences involving Enter was immediately discernible over BEAKL Ti’s use of the Shift Space for the Enter key, especially for common chord sequences .

However, the loss of the Backspace on the base layer for BEAKL Vi felt somewhat of a compromise whose (ingrained) usage not uncommonly requires multiple taps when needed (for the imperfect typist). What to do?

By relaxing the original BEAKL Ti layout’s fixed Shift Space assignment for Enter, save for the base layer – which is preferred for the added security it provides from accidental “prompt” confirmations (*nix administrators know of what I speak) – and floating the Enter key position so that it consistently falls under the right thumb for a given layer, key chord or sequence (a mouthful, I know, but more clearly presented below), the benefits of BEAKL Vi can be achieved and more. Brilliant!

The following layer illustrations denote the new Enter key placements and other firmware optimizations (with some lesser used features removed in the process). Refer to the original BEAKL Ti for comparison and the remaining mouse, toggle and steno layer descriptions..

base layer

Tap key actions for..

keycode	double tap	double tap (down)	triple tap
Colon	Colon Minus
Backspace		repeating Backspace

thumb shifts

Tap key actions for..

keycode	double tap	double tap (down)	triple tap
Tilde	Tilde Slash

Where necessary, tap dance keys use double tap (down) to provide repeating characters. Alpha modifiers on the home row and thumb do not – not generally being used for line decorations.

rolling thumbs

Enter after a Tab or Shift-Tab sequence can now be keyed by holding the Tab key down on the last tab and tapping the same right thumb key..

home row shift

dot chords

Tap key actions with Dot* key down for..

keycode	single tap	double tap	triple tap
Space	Dot* Space Shift
Enter	Dot* Enter Shift	Dot* Enter Enter Shift

*Where “Dot” is Period (base layer), Question (thumb shift) or Exclamation Mark (home row shift). The chord acts as a one shot modifier, capitalizing the next keystroke.

thumb symbols and cursor

immediately following any cursor movement, raising the left thumb Shift Layer – I down – treats the Delete key as an Enter which is cleared upon the first non-Delete key, allowing successive Enter’s to be typed. This is purely a pick list convenience saving a lateral movement of the right thumb. Hint: for Delete, see Home Row Shift, or key NOP (grey) to clear the Enter action beforehand..

Tap key actions for..

keycode	double tap	double tap (down)**	triple tap
Colon			“ :: ”
Less Than		repeating LessThan	“ <- ”
Percent		repeating Percent
Greater Than		repeating GreaterThan	“ -> ”
Equal			“ /= ”
Asterisk	Dot Asterisk

**The down modifier state for the key necessitates a double tap (down) to distinguish a repeating character. Note: a repeating Tilde is available on the Home Row Shift.
