Vim: create marks across files?
vim
Solution
Yes. Use capital letters for the mark.

Marks can span across files. To use such marks one has to use upper-case registers i.e. A-Z. Lower-case registers are used only within files and do not span files. That's to say, if you were to set a mark in a file foo.c in register "a" and then move to another file and hit 'a, the cursor will not jump back to the previous location. If you want a mark which will take you to a different file then you will need to use an upper-case register. For example, use mA instead of ma.
Problem
A feature I often use in Vim is `m`ark and jump-to-mark (`'`)… But they only work within a file. Is there any way to create a mark which works across files? For example, so I can create mark `a` on line 42 of `foo.py`, then jump to that mark while I'm editing `bar.py`?
