In the process of tweaking my uzbl config to be a little more vi(m)-like, I've made several modifications:
<<, >> (scroll to begin, end) are replaced with the more correct gg and G
b, m (next, previous page) are replaced with vimperator's H and L
t opens a new tab in uzbl-tabbed, so I removed it from the config
B (add bookmark) replaced with the more correct m
u (load bookmark) replaced with the more correct `
y2url is just long; y is the original vi(m) for it anyway
:q should also exit; unfortunately, this happens immediately and I haven't figured out how to require pressing
Swapped case on F, fl, and FL to match vimperator better
And finally, since google.com automagically moves the focus to its input area, I commented out the "home page." gh still goes to google, though.
I used to have ^W,h and ^W,l switch between tabs, but haven't gotten this to work correctly in the latest version of uzbl yet. Instead, Ctrl+Tab and Ctrl+Shift+Tab move between tabs.
And, of course, the colors have been modified. I find the color scheme I've got helps improve readability. It also color codes based on SSL/non-SSL, even with tabs that aren't selected.
