# Hints¶

kitty has a hints mode to select and act on arbitrary text snippets currently visible on the screen. For example, you can press ctrl+shift+e to choose any URL visible on the screen and then open it using your system browser.

URL hints mode

Similarly, you can press ctrl+shift+p>f to select anything that looks like a path or filename and then insert it into the terminal, very useful for picking files from the output of a git or ls command and adding them to the command line for the next command.

The hints kitten is very powerful to see more detailed help on its various options and modes of operation, see below. You can use these options to create mappings in kitty.conf to select various different text snippets. See ctrl+shift+p>f for examples.
