Introduction
Helix uses HJKL for basic movement. :w is used to save, :q is used to quit. When doing these shortcuts helix will also show the command menu with some relevant docs or autocompletions
Something that differentiates Helix from Vim is that Helix is is based on the subject-verb pattern versus Vim that uses the verb-subject pattern for commands

Shell Commands
Running shell commands from the terminal is possible using :sh followed by the command. You can also insert the path of the active file using <Ctrl+r>% to paste the data from register % which contains the current file path
So you can run a command with the given file like:
:sh command <Ctrl+r>%
Which will pass the current file to the shell command
