This could be done through a simple right-click on the Editor field.
Similarly, an option to just display the current value (if the debugger were running) without setting a permanent watch, either in a dialog or a tooltip.
Possible to do as a module as well.
[jglick] Does this already exist??
[Hanz] Added to the pop-up menu of the editor.
Verified in Pilsen (build 010301) and Forte 2.0 (build 1160).
Resolved for 3.4.x or earlier, no new info since then -> closing.
