Currently if you have a string in a field somewhere like "%drive%\%directory%" you can put your mouse over it to see the evalution in a tooltip. But it doesn't work the best because the tip disappears after a few seconds and you can't copy it to the clipboard or anything. Would it be possible to:
1) Show the evaluation in the status bar rather than a tooltip (or perhaps both)
2) Add a right-click menu option to copy the evaluation to the clipboard?

Sorry if this a stupid question, but why do you need to copy the evaluated expression to the clipboard?

Some scenarios:
- the variable expansion corresponds to the location of a program which is run (so I can then paste it into the start/run box)
- the variable expansion is the name of a document
- the variable expansion has some complicated escaping/quoting issues and I want to break it down and check that it’s being assembled correctly
- it’s a set of command line parameters and I want to check that it’s right, perhaps by passing it manually on a command line.
