This is the thing with global keyboard shortcuts implemented as keyboard
listeners: Events get duplicated. You might want to defer the spawning of
the file list tool until the next world cycle via (pseudo code):

self future spawnFileList.

or

Project current addDeferredUIMessage: [self spawnFileList].

Or something like that. Then, this behavior is less likely unless the user
insists on pressing the keys for too long (see: key repetitions).

Best,
Marcel
