[Shift] + [Arrow] key usage with chart ranges
 

Greetings and TIA for yor time
Here's what i'm doing:
Right click on a chart
Source data
series tab
click on any series address box at the right hand (red arrow)
A flashing broken line will appear around the relevent range
If I now want to extend the series address range I must use the mouse, since
the shift, arrow, and end keys do not function in this context on my setup.
Can i change my configuration to enable use of the shift, end and arrow keys
(much easier on large data ranges)?
