I am used to use the numeric keypad for navigation (e.g. : [KP7] -> Start, [KP1] -> End, [KP4] -> Left, etc… ).
I am also used to use it for selection (e.g. : Shift+[KP7] -> Select from cursor position to beginning of line, Shift+[KP1] -> Select from cursor position to end of line, etc…)
With the keyboard configuration installed with Ubuntu, though, Shift+[KP7] prints the character "7", Shift+[KP1] prints "1", etc…
How can I change this so that Shift+[KP-key] is not mapped to [key], but to Shift+[KP-key] ?
I finally found out there was a standard ubuntu option to set this :
EDIT 1: In newer versions (eg.Ubuntu 18.04) look at Tweaks> Keyboard and Mouse>Additional Layout options>Miscellaneous compatibility options>"Num Lock on: digits; Shift for arrow keys. Num Lock off: arrow keys (as in Windows)"
EDIT 2: Or, as suggested in XUbuntu: Make Shift+NumPad work like Windows
Use the following command as workaround:
setxkbmap -option 'numpad:microsoft'
In order to run the above command automatically when starting the graphical desktop environment, create an Application Startup entry:
