I started a job (moving cities for this new job) in 2004 and found my boss (at that time, a grizzled old veteran of computing) using BRIEF.

I recall him trying to convince me to switch to it a few times, from vim. I never found it as advanced as vim, but I could see the capabilities. I recall being impressed by some macro he had that improved navigation, both within a file and opening new files.

I also recall him being impressed when I showed him vim's ctags commands.

Good times. Pity he was a mean SOB.
