mapping a layer to a modified key

[nyxmeowmeow]

hi how can i make a key like M-t or C-l activate a layer? ive tried a few different ways but havent been able to get it to work

[gerhard-h]

(defalias
t (switch
   (lmet rmet) (layer-switch layerT) break
   () t break
)   

This does what you ask for, but is it what you wanted? How to leave layerT?

(defalias
t (switch
   (lmet rmet) (layer-while-held layerT) break
   () t break
)   

With this one would realease the layer when t is realeased.
When lmet should control the release and should not be active in layerT you can use virtual keys for lmet and (layer-while-held layerT).

im already using tap-hold-press on the super key:

  lm (tap-hold-press 120 120 esc lmet)

[gerhard-h]

maybe

(multi 
(tap-hold-press 120 120 esc lmet)
(on-press vkey-press vmet)
(on-release vkey-release vmet)
(on-release vkey-tap f13) ;; press any key (on windows) to avoid triggering a singular lmet 

or simpler

(multi 
nop1
(tap-hold-press 120 120 esc lmet)
)

and

win (switch
    (nop1) (layer-while-held win) break
    (lmet rmet) (layer-while-held win) break
    () g break
  )

[nyxmeowmeow]

neither of those work, it just presses super g like normal as all the keys were default behaviour

[gerhard-h]

it works in simulation simulate
