In gnome-terminal using the next/previous tab keyboard-shortcut when on the last/first tab causes the shortcut text to be 'typed' into terminal window. This is undesirable since (for instance) in vim, the default CTRL-PAGEUP command causes a change in the case of the text under the cursor. Preferably when on the last/first tab these shortcuts are ignored. Reproducible: Always Steps to Reproduce: 1. Open multiple tabs 2. Travel to the last tab. 3. Use the next tab shortcut 4. The 'text version' will be typed in. Actual Results: The 'text version' of the shortcut will be typed in. Expected Results: Ignored the input shortcut input and not 'typed' it into the terminal.
upstream problem really. Although it may be intentional, passing on the keypress if it's not used.
