PPGP issue #21: SALOME hot key buttons get catched in several GUI components
Some common keyboard shortcuts like Ctrl+A or Shift+A where intercepted by SALOME GUI if pressed in PPGP Python editor based on QScintilla. Also it was impossible to type capitals with Shift.
Solution implemented:
- Ctrl+A shortcut for "Save as" replaced with Ctrl+Shift+S
- Shift+C for "Close window" replaced with Ctrl+F4
- Other shortucts like Shift + letter replaced with Alt + Shift + letter.
