Vim Shortcuts

#It might be the case you have redefined the shortcuts. But this is what the default is.

Ctrl+A: move to the start of the current line
Ctrl+E: move to the end of the line
Alt+F: move to the end of the next word
Alt+B: move to the start of the current or previous word
Ctrl+T: swap the two last characters, e.g.: sl<C-t> → ls
Alt+T: swap the last two words, e.g.: foo bar<M-t> → bar foo
Ctrl+U: cut the text of the current command before the cursor.
Ctrl+W: cut only the word before the cursor.
Ctrl+K: cut the text of the current command after the cursor.
Ctrl+Y: paste the previously cut text after the cursor. 

This is useful when you have typed a long command and realize that you forget to do something before, e.g.:
% ./my_long_command -v -u foobar -t -x<C-U>
% ./do_something_before
% <C-Y><enter> # paste and execute ./my_long_command…

Alt+U: uppercase the next word, e.g.: ls<C-a><M-u> → LS
Alt+L: lowercase the next word, e.g.: LS<C-a><M-l> → ls
Alt+C: capitalize the next word, e.g.: foo<C-a><M-c> → Foo
Ctrl+L: clear the screen, leaving the current line at the top.
Ctrl+_: undo (incremental).
