As the title suggests, I want to rename several tags only in agenda files.
So, a tag1 will become tag11, taga1 will become someothertag, etc.
I can do it with
C-a m tag1 * B + tag11 RET C-a m tag1 * B - tag1 RET
But that is too cumbersome, especially, if you have to do it for several tags.
Any other quicker methods?
