I have no mouse enabled and find it rather difficult to find a really comprehensive list of shortcuts for firefox. I imagine there might be some way to have every user interface command mapped onto a shortcut. But where can I find information about it?
This is a list of keyboard shortcuts in Mozilla Firefox: http://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly
For example, Ctrl + Shift + H opens the library windows (History)
