v9.1 on Linux Mint 22 Cinnamon.

When a query is running in the query tool I press Alt+Shift+Q to cancel the running query. This unexpectedly opens a new query tab. (It also cancels the query, as expected, but this is not immediately obvious, since I'm suddenly looking at a new, blank query tab!)

A shortcut key should not do 2 things. The default shortcut keys for these should be different, and an application probably shouldn't even allow the user to assign the same shortcut key to two things, or at the very least warn the user that two actions will happen when they press the key combination.

I would suggest that it's the cancel query shortcut that should change - perhaps to Shift + F5 to mirror the F5 used to run the query, but that shortcut key is itself problematic when pgAdmin is run in a browser, as that's a very commonly used browser hotkey for reloading the page.

Note that it is useful to have a shortcut key that opens a new query tab in this context - while one query is already running, I want to run another - so please do not "fix" this by preventing the "new query tab" shortcut from working while the focus is in an existing query tab, even if that has a query currently running.
