UDC enhancement.

[chris28]

Sir,

This is in regard to "assign keyboard shortcut" in UDC.
As one might have lot of files named,starting with the same letter e.g
debit1,drafts... and if there are above 6 files then assigning ctrl+shift+alt+d...
to open the files incurs difficulty,which instead can be made possible by
adding shortkeys like d1,d2,d3 ..etc in KS.
