Simultaneous while mods are held

[roubaobaozi]

Hi,

I was hoping to have a simultaneous like so:

[[:i :o] :delete_or_backspace]

However, I was hoping to pair it with mods eg. option held, io same time, yields option+backspace which deletes word, or cmd+backspace deletes to start of line.

I had tried same syntax as other places so

[[:##i :##o] :##delete_or_backspace]

But it breaks at compile time.

I tried different combinations of things (eg. [[:left_option :i :o] :delete_or_backspace] which only works when all 3 are pressed simultaneously or [:left_option [:i :o] :delete_or_backspace] which seems to just activate on either left_option or io) but nothing seems to work.

I was hoping you'd have some insight on this :)

Thanks
