In a default configuration, the command Set UTILITY=Find,Toggle is assigned to Tools -> Find Panel.
Repeatedly clicking Tools -> Find Panel toggles the Find Panel on and off.
However, if a hotkey, say F3, is assigned to the menu item, pressing that key activates the Find Panel, but pressing the key again doesn't remove the Panel.
Is this a known limitation of Toggle in conjunction with keys?
I can't recall if I reported this issue to GPsoft or not - so open a support case on their website for it...
The "issue" is that the hotkey you assign to the command (on the existing Tools menu item or your own hoteky definition, doesn't matter how you do it) is being "trapped" by the Utility (Find) Panel... i.e. as soon as you toggle it "on", focus is being switched to the panel, and the keystrokes you're running to toggle it "off" are being captured by one of the fields of the panel (by default, by the "Name matching:" field of the Find Panel).
Ideally, GPsoft would make a change such that "specially" qualified hotkeys (like Alt, Ctrl, or Win keys - i.e. keys that you wouldn't "need" to use to enter information into the panel fields, or navigate between fields in the panel) would be passed out of the panel so things like hotkeys could still function.
Exactly as steje says. This will be fixed in the future but at the moment the only solution is to make the hotkey global (in which case, you probably wouldn't want to use F3).
