> - `tab` inserts the current selection in the input. Do you mean something else?
In emacs (specifically ivy/helm), tab in context-sensitive. Using tab on a command input autocompletes that input, where elsewhere it behaves differently. There doesn't actually seem to be a nice way to select from the command lists given (like the session selector) without typing it in, and that means I have to type it in in full, which is awkward and cumbersome.
One final note is I just tried using it again -- first problem is duckduckgo.com does not load, I just get a blank page after it says "finished loading". The other is that the default key of 'd', I had assumed would close the buffer, but I guess that must be 'x' because it closed the entire window, which I would have expected from 'q'.
