French Tablature: some letters don't work

Please will you report problems with nightlies either in the issue tracker or the Technology Preview forum.

Support and Bug Reports is supposed to be for stable releases.

This prevents confusion by some users because they can't find a feature present in the nightlies but not the 1.x stable release.

*) H: The issue with 'h' is indeed a shortcut conflict with another function (crescendo, in this case) being assigned the same keystroke in the default setup. Possible solutions:

• the user who regularly needs French tablatures redefines the Crescendo shortcut to something else (but should be informed in some way of the need to do so);
• a different shortcut for Crescendo is provided as a default
• the Crescendo shortcut is limited to non-tablature edit mode

*) I/J: The default letter shortcut for the 8th fret is [J], as [I] is already used by default setup for [I]nstrument (as it can be discovered by looking at the "Edit | Preferences | Shortcuts" dlg box).

*) M-...: Shortcut for frets greater than 9 are not even defined. Possible solution:

• Shortcuts for frets greater than 9 (10 - 13?) are defined in the code, but not assigned any key by default; the user needing this feature may assign the key(s) he prefer (and manually resolve the conflicts which would arise almost inevitably).

However, I cannot confirm that a wrong letter is entered by using one of those key strokes; rather, nothing is entered as the shortcut is simply reject by the framework.
____________________

As a (temporary?) work-around, note that both number and letter shortcuts are always active during tablature entry, as they refer to the fret value regardless of how this value is displayed. So, the 10th fret can always be entered with [1] + [0] (and so on for higher frets) and will be correctly displayed with digits or letter according to the staff setup.

In general, shortcuts for tablatures have always been a source of problems and, as far as I know, no definitive solution has been found and proposed.

The number of needed shortcuts is relatively high (about two dozens for the fret values only, plus other to move around in the tab, to select/change the note duration value, to increase/decrease the pitch or string of a note, etc.) and many obvious choices for these actions are already assigned to general programme functions.

Currently, a partial solution is implemented which 'filters' shortcuts according to the programme mode; for instance, shortcuts to enter notes based on pitch ("A", "B", ...) or on interval ("Add a second above", "Add a third above", ...) are disabled in tab. entry mode, as they have little use in tabs. Some of them have been disabled just because their default keystroke happens to be 'needed' for tablatures (like "enharmonic up", to 'free' the [J] key). In addition, this requires special code and setting juggling at each change of programme state, as Qt shortcut machinery has no notion of "state" (see //github.com/musescore/MuseScore/blob/master/mscore/musescore.cpp#L2477 ).

This is rather clearly sub-optimal, but I've run out of solutions and I still hope someone will come up with a genial breakthrough. Anybody volunteers?

Thanks,
