Add keyboard arrow keys navigation to Custom Key Signature Editor
At the moment, user can only grab accidental and place it in editor by mouse. Moving is possible only by mouse. This functionality would remain unchanged.
User practically have no chance to accurate place accidentals. If wants to do so, needs to manualy edit mscx file.
Enhanced functionality would be:
1. Inserting accidentals
when user click accidental, it will be added to key signature
accidentals would be inserted this logic:
- in the middle of the staff lines ("y=2")
- each at x+1 position , 1.st "x=0", 2.nd "x=1", ...
2. Moving accidentals
user can move selected accidental by arrow keys
default vertical step is 0.5 (sp) ↑, or ↓
octave vertical step is 3.5 Ctrl + ↑, or Ctrl + ↓
default horizontal step is 1 →, or ←
little step 0.1 Ctrl + →, or Ctrl + ←
selection change (walk thru inserted accidentals) Alt + →, or Alt + ←
Note: This is simple enhancement of curent editor, which can helps users a lot.
I am also thinking about more complex Custom Key Editor, with logic, which covers all other tasks (multiple clefs, transpositions, ...), but I need to rethink it a bit more firs, than I will post my thoughts to forum as separate thread.
