Improving home row shift for optimal layouts

[gerhard-h]

After setting up aliases (tap-hold-release 1 140 j rsft ) and (tap-hold-release 1 140 f lsft ) you are done...

But now typing "Fjord" rather fast and I ended up with "Ford".
Same for After, Often, Ajax,... they all require this double tapping.

I can not say if it is a bug or me messing up the timing, I didn't even realize there being a problem because [A-Z][fj] words a rare (1 in 300 in my example text)
But using a layout like Colemak, Dvorak,... f and j will be replaced with n,t,e,... and the probability changes to 1 in 8 (upper case words).

The solution I found is: n (tap-hold-release 1 140 n (one-shot 500 rsft) ) and it works perfectly without any side effects.

EDIT
When rolling (to slow) over the shift key causes D instead of fd for you
(tap-hold 1 140 f (one-shot 500 rsft) ) may solve that as it favors rolling for some extra milliseconds.

tap-hold's first timer parameter is still a little mysterious for me, but setting it very low, seems to make tap-hold and tap-hold-release to do very much the same otherwise.

EDIT tree month of typing practise have passed and I realize that I have learned the shift-timeings (without special training) and don't need the help of one-shot any more (tap-hold 1 160 f lsft)

I tried your approach and that indeed works like a charm for most of my usecases, thanks a lot!

I noticed, however, a slight problem - I guess that's a more general problem with all kinds of home-row mods - vim-like navigation does not work well with "hold" actions on j. Fast consecutive presses of j get sometimes interpreted as J, which is a join-line action in vim. And one can not really hold j for going down the buffer, since vim never gets repeated keypresseses.

It never happend to me, but if you release j after 140ms (but before 500ms) and tap it again within 500ms oneshot is triggered and you get "J".

Simplest solution: Type faster :)

Simple solution: decrease the 500ms value
I only tried 400ms, it got harder to get the "J" but still was possible.

Here is my initial, more radical solution:
(tap-hold-release 1 140 (fork j (unicode j) (rsft) )(one-shot 500 rsft) )
this means if you try to Right-Shift j you always get (unicode j) wich is lower case.
I don't use vim, but if it hates unicode try XX
