Alt+i toggles sidebar even though no keyboard shortcut is configured.

Pressing Alt+i toggles the sidebar even though no such keyboard shortcut is configured. I want to bind Alt+i to another action, but when I do and press Alt+i i get a dialog telling me that the key sequence is ambiguous.

The dialog suggests that I use 'Configure Shortcuts' to solve the ambiguity, but there is no way for me to do that since only one action is associated with Alt+i.

It would be helpful if the dialog would tell me which actions it thought were conflicting.

Have tried removing ~/.config/QtProject but the problem remains.
