Today I was typing a command in the Xfce terminal and found that if I typed letter 'f', a new tab opened.
So I looked in the menus and found a "Shortcuts" tab and a setting there to make letter f do this.
My question is, how did this happen? No one else uses this computer, and I had never changed anything in the keybindings, and I have previously typed 'f' without triggering a new tab (actually I'd never used tabs but just opened new terminal instances)
I searched here with keywords 'terminal shortcut' and did not find any posts about a mysterious new appearance like this.
