Sometimes I use marks to navigate easily through different files using
And sometime (more often than I'd like to admit) because of inattention or whatever the reason is, I use
m[LETTER] with an already existing mark which erase its previous value when I don't want to. Most of the time when I do that I don't have open the file originally pointed by the mark.
In this case when I immedialy realized that I made a mistake, is it possible to get the previous value of my mark other than remembering where it was pointing to, navigating to this location and setting it again?
I haven't found a command like that in the doc so if that doesn't exist is there a clever workaround that some of you use in this situation?
