multiple timing schedules selectable by cursor

I got a n00b question regarding timers and such.

I want to have a mulitple timing schedule and other various functions selectable by cursor, so lets say "phase 1" will have one type of schedule and "phase 2" will have another and so on. I have set up a cursor up and down type of loop with counters but how do I pass the information to the timers?

Do I use one timer for each type of program and use flags with "or" circuits?

Here is a possible solution proposal.
With the cursor keys up / down you can choose between 4 values.
The 4 values on the display even changeable.

For 0BA7 or 0BA8

0BA8

Yeah, I ended up doing something similar.

The problem now is that I am running out of buttons on the PLC. Can I program the "ESC" or "OK" buttons on the PLC? The only stuff that is available in Logosoft are the cursors and the TD function keys F1-F4.
