I have several tabs open. One tab contains a text file. I cut some text. Then I
did another cut. And a few more.
Then I went to the other tabs and did a bunch of work on the data in them -
cutting, pasting, moving things around. I did this for a couple hours.
Then I went back to the first tab.
Hi Roger,
Right, like in most editing applications each opened file has its own
undo/redo stack of changes independent of the other opened files.
In the Preferences->"Editor" page there is an undo history size setting
which limits the undo history for each opened file to a maximum of 200
