How to implement Tap - Hold - Long_Hold - Double_Tap_Hold

[gerhard-h]

Nesting tap-hold abc (tap-hold 140 140 [ (tap-hold 200 300 (macro b) (macro c))) gives a quite horrible user experiance because
there is no visual feedback during the Hold periode.

but when nesting tap-hold inside multi you can clearly tell if you get 1 or ! or !! because they appear one after the other
1 (tap-hold 200 300 1 (multi (macro S-1 ) (tap-hold 200 400 XX (macro S-1 ))))

EDIT with the new feature macro-release-cancel it gets much simpler (macro-release-cancel 1 140 S-1 400 S-1 ) but it's still a good idea to start out with an tap-hold because this is much snappier.
1 (tap-hold 1 140 1 (macro-release-cancel S-1 400 S-1 ))

EDIT in most cases you don't want autorepeat on a tap-hold key. You achive this by wrapping the key inside a macro.
But for m * ****... I wanted Delayed_Autorepeat
m* (tap-hold 140 140 m (multi (macro S-= ) (tap-hold 200 700 XX S-= )))

by using backspace even 1 or ! or @ works (wich is surprising as I suspected to get S-A-C-q)
1 (tap-hold 200 300 1 (multi (macro S-1 ) (tap-hold 200 400 XX (macro bspc A-C-q ))))

even Very_Long_Hold is possible 0 or = or == or ===
0 (tap-hold 140 140 0 (multi (macro = ) (tap-hold 200 300 XX (multi (macro = ) (tap-hold 200 500 XX (macro = )) ))) )

for home row mods Long_Hold makes little sense, but you could use Double_Tap_Hold f or shift or ]
(tap-dance 140 ((tap-hold-release 140 140 f lsft) (tap-hold 200 240 (macro f f) (macro A-C-9))))

also tap | hold | long_hold | dbl_tap | dbl_tap_hold is possible
-_~: (tap-dance 140 ((tap-hold 10 100 - (multi (macro S-- ) (tap-hold 200 400 XX (macro bspc @til ))) ) (tap-hold 10 100 (macro - -) (macro @: ))))

EDIT Meanwile kanata supports nesting tap-dance inside tap-hold wich is much better because you can set longer tap-dance timings without affecting tap-hold and tap-hold (the outer one) will be much snappier.
-_~ (tap-hold 10 100 (tap-dance 160 (- (tap-hold 10 100 (macro - -) (macro @til)) (tap-hold 10 100 (macro - - -) -) )) (multi (macro S-- ) (tap-hold 200 400 XX (macro bspc @til ))) )

P.S. don't combine multi with unicode (tap-hold 140 140 1 (multi (unicode ! ) (tap-hold 200 400 XX (macro bspc A-C-q ))) ) because kanata will crash on holding now.

In the latest version, people will likely want to use macro-release-cancel instead, which is a feature that was inspired by this discussion.
