#102 Save Segmentation Image shortcut does not work in paintbrush mode

[ABiancardi]

When in paintbrush mode (4), the keyboard shortcut ^S (save segmentation) does not work (whereas it does work while in the other modes).
Checked for version 3.6.0 on CentOS andWindows-10.
On CentOS the following error message is displayed:

QAction::eventFilter: Ambiguous shortcut overload: Ctrl+S

Thank you,
Alberto
