How to insert tab characters for indenting in MathScript Code

[wildcatherder]

Since pressing the Tab key throws one out of Text Mode, when editing a MathScript Node, is there some other way to introduce a tab.  Tabs are extremely handy for improving readability of nested loops and inserting the equivalent number of spaces is time-consuming .

Can you edit the script in the MathScript window (Tools » MathScript Window...)? The tab button works like that from there.

That is a good idea but I've already inquired about moving code back and forth between Window and Node.  The only way to do it is to save as a script and then load it into the other, which makes for awkward editing.
