15350,"Cannot use , (comma) as a shortcut key",CraigK,,"Trying to use comma as a shortcut key (In this case for show-menu-bar >>> File - preferences - input - virtual machine - show-menu-bar - HOST+, (comma))

While the comma can be used as a shortcut, it no longer works after restarting VirtualBox and isn't visible in under file-preferences-...

Looking in %user%/.VirtualBox/VirtualBox.xml <ExtraDataItem name=""GUI/Input/MachineShortcuts"" value=""..."">
The keyboard shortcuts are saved in a comma-delimited list, so it just sees the comma as an extra delimiter, and fails to read it.

I worked around this by using < and > as shortcuts, as opposed to , and .

I might get to submitted a code fix, but low priority so I will just log the issue incase someone else is already in that section of code",defect,new,GUI,VirtualBox 5.0.16,,,,Linux,Windows
