Question

Lets say cursor is standing on line #10:

foo bar “fizz” buzz

first character.

How can I yank fizz using ex mode (to do the same as f"yi" would do)?

Bonus points for ability to specify register.

Answer 1

You can execute any normal mode command via :normal (add ! to ignore any mappings; a good practice when writing plugins).

:normal! f"yi"

For special keys, enclose the command in :execute, as in:

:execute "normal! aText\<Esc>"
