This is a way to do it but it is kind of klugy.
With the account open in RP, select "print" from the main toolbar.
Select "this account" and select "preview", not "print".
Select rules only.
Then in the upper left corner, select export (an envelope looking icon).
Select "text" format, and to "application".
It will then open Wordpad and paste the rules to there.
You can then select, copy and paste at will...just like this:
1 WHENEVER F4 KEY ON ANY KEYPAD ACTIVATES
THEN TOGGLE F4 button light (Out 24)
2 WHENEVER F4 button light (Out 24) STATE IS TURNED ON
THEN DISABLE NON-ALARM VOICE MESSAGES
3 WHENEVER F4 button light (Out 24) STATE IS TURNED OFF
THEN ENABLE NON-ALARM VOICE MESSAGES
THEN ANNOUNCE Miscellaneous 5 (vm243)
4 WHENEVER F4 button light (Out 24) STATE IS TURNED ON
THEN DISPLAY "Silent Mode^M" IN Area1
5 WHENEVER F4 button light (Out 24) STATE IS TURNED OFF
THEN CLEAR PREVIOUSLY DISPLAYED MESSAGES
