VimPlugin: Vim-Signature

From wikinotes

Allows you to mark places in a file so that you can quickly navigate back to it. PERFECT for text files, notes.

NOTE:

information is stored in .viminfo, which is unique to each computer. Unfortnately, that makes this useless to me. I'd recommend writing notes in ReStructuredText, and using TagBar or code-folds to navigate them.

[a-zA-Z]   "pressing m and any alphabetical key will tag the current line with that letter
'?         "'"jump to tag from a list of all tags in the file.
m-         "delete comment from current line
m<space>   "delete all tags in current buffer (file)
