TSE: Linux: Feature: Request: RollLeft() and RollRight keys

[knud van eeden]

Hello,

In the tse.ui in TSE for Linux version 4.50.13 (on Linux non-WSL Ubuntu) currently defined are:

<Alt F5>                RollLeft()

<Alt F6>                RollRight()

But when using the xterm terminal for example

running showkey does not detect those 2 keys

(because e.g. used by the terminal / windows manager / operating system instead).

So requested is to ADD to this tse.ui these 2 alternative keys:

<Ctrl F5>                RollLeft()

<Ctrl F6>                RollRight()

This because <Ctrl F5> and <Ctrl F6> are not

used elsewhere in tse.ui and also

they are instead correctly detected

in showkey.

Note: a similar solution of adding working keys instead 

      was already implemented for mPrevPara() and mNextPara().

Thanks

with friendly greetings
