How do I log all Vim verbose output to a file to diagnose slow startup or plugin issues?
:set verbosefile=/tmp/vim.log verbose=9
Vim's verbosefile option redirects all verbose tracing output to a file on disk instead of printing it to the screen.
Tag: verbose
How do I find which plugin or script defined a specific mapping?
:verbose nmap <leader>
The :verbose prefix on mapping commands shows not just the mapping definition but also the file and line number where it was defined.
How do you find where a key mapping was defined?
:verbose map <key>
Use :verbose map to see the mapping definition and the file/line where it was set.
