I used ZScript to create an [IPalette] panel and then assigned a shortcut key to it.
I found a case which states,
[IPalette, pluginName,1, 1387] // Alt+Shift+K - assign hotkey to the palette
I wonder how the “1387” in [IPalette] is determined to be the “Alt+Shift+K” shortcut key. I’ve searched all the official documents but couldn’t find the answer. Could you please tell me where I can find the document about this shortcut key?
