OK this isn't going to affect everyone, but I have had to uninstall the Logos Greek keyboard because the <Alt+Shift> shortcut messes with other software e.g. Adobe Illustrator CS5. Alt+Shift is a common combination in Illustrator and other packages which make heavy use of modifier keys, and it when Greek kbd is active, Illustrator's keyboard shortcuts disappear until the English kbd is restored.
A simple F2 or equivalent, as per L3 would be much better.
Thanks
