Christophe de Dinechin ae73146878 Add transient alpha mode ... After a lot of experimentation, it turns out that it's not really possible to use the shift key as originally planned, because it is not reliably visible when two keys are simultaneously visible. It can only be combined with key N and O (and maybe a few others), and these combinations are clearly treated specially (they give some magic keycode, e.g. screen snapshot with Shift-DISP on the DM42). It turns out only three keys seem somewhat reliable in combination with alphabetic keys: ON, UP and DOWN. On works with _almost_ all keys, but apparently B or C is missing (forgot which one). Up and Down work with all alphabetic keys. This turns out to be a good thing, because it gives us an additional option that was not originally planned: quick access to lowercases. The behavior implemented in this commit is therefore the following: - "Up" held with any key gives an uppercase letter - "Down" held with any key gives a lowercase letter. A minor side effect is that up and down are now active on release and not on key press. In practice, this is barely noticeable.
