Is there an example of using command flush-lines or keep-lines

[zhaohe wang]

I want a help for the commands for I don't know how to use the regexp.

Thanks a lot!

I don't know anything about these commands, but their source in LeoPyRef is marked "(doesn't work)".  I would, though, like to know what "Transient Mark mode" is.

So would I :-)  I am going to delete these commands.

I have just deleted the flush-lines and keep-lines commands. They are not needed and may never have worked.

PR #2941 deletes these two commands. It has been merged into devel.

Might that mean that after an operation, the "mark" is removed from the affected nodes?  And is there anywhere that actually can happen (except for deleting a marked node)?

There seems to be no way to answer the question. The two commands used ec.linesHelper, but there is no indication of any "mode" anywhere in linesHelper. I am about to delete linesHelper also.

My guess is that these commands are ancient holdovers from emacs emulation code. Anyway, Leo will be better off without the commands and their helper.
