Enable layer with modifiers active

[xauser]

Hello,

I'm looking for a way to have a key that switches to a layer and has two modifiers enabled. In TMK this is done with macro ACTION_LAYER_MODS.

I found this thread ZMK Issue that says it's possible using macros (example ZMK Doc).

I tried my best to configure this in the keymap-editor macro section and assign this macro to a key on my keymap.

When I press 'save' the build fails with...

devicetree error: /keymap/default_layer: undefined node label 'lm'

I think the #ifndef VERSION_MACRO/#endif is excluding it from the compile code. If you don't want to get rid of that altogether you can just manually move your macro after the #endif line.

I replaced the macro created by the editor with the one from the zmk doc and moved it below the #endif and that worked. It would be great to get this done with the editor some day.

It would but I can't overstate the complexity of trying to support the C preprocessor at the same level as devicetree. I go into some of the problems here: https://github.com/nickcoutsos/keymap-editor/wiki/Preprocessor-Support
