in cases like that I would make a maxscript and bind it to a key since than I could have it do different things based on the selection type and what is currently selected. pretty easy to get info about the selection and string a few if and then statements to the key.
Is there a way to bind two commands to the same hotkey? When you're in specific Selection Modes or Dialogues it seems practical. Also why is there no hotkey for bridge :(
