Hot-keys for faster navigation in subiquity's keyboard dialog (and maybe other dialogs) desired

It would improve the navigation in the keyboard configuration dialog,
if the cursor would jump to the Layouts and Variants that start with "n" in case the 'n'-key got pressed.
Means pressing "g" would jump to "Georgian" - the first entry that starts with g,
pressing 'j' would jump to "Japanese" etc.
