As usual, have to write the same thing four times ☹
The parentheses around `q` tell the hotkey/keymap code to ignore
auto-repeat events (which works fine in Chrome but not in Firefox, I
reported the bug https://bugzilla.mozilla.org/show_bug.cgi?id=1900397
)
In addition, I've added a guard variable that is true while calling
the backend to boost/renote, and false otherwise. This way, even in
Firefox we don't spam-boost. Unboosting is still *only with the
mouse*, I have not added that functionality.
