we don't have any support for doing something like ydotool calls (the wayland compatible variant of xdotool) in response to keybind being pressed.
You can use an unused key code for this purpose. So instead of emitting a KEY_FOO, you write 0xbeaf (or anything) that you can handle at the other end of the pipe. You see that key 0xbeaf is down and you can start a process. When key 0xbeaf is up, you just ignore that event. It is basically a map rule that ignores key but does some custom stuff.
{ .keys = { KEY_SHIFT, KEY_ESCAPE }, PRESS_ON_DOWN(KEY_SHIFT, KEY_GRAVE), DOWN_IFF_ALL_DOWN(2) }
PRESS_ON_DOWN(key) takes only one argument. It means that it presses key (down event followed by an up event) when this rule is toggled down and nothing when up. Basically a one shot key. (At least it should do so according to docs and my memories. :))
You would need two-two down and up events fired, that currently is not possible.
I would say you need something like this:
{ .keys = { KEY_SHIFT, KEY_ESCAPE },
.down_press = { KEY_SHIFT, KEY_RESERVED, KEY_GRAVE, KEY_RESERVED },
.up_press = { KEY_RESERVED, KEY_GRAVE, KEY_RESERVED, KEY_SHIFT },
DOWN_IFF_ALL_DOWN(2) }
And here is the patch for it:

Just curious, but if you don't need the physical escape key (caps2esc, etc.), wouldn't this work if you just map Esc to the Grave character?
EDIT: Just tested it, it works.
