I keep BBEdit's option to emulate Emacs key bindings disabled, because I don't know most of them and some of those combinations I want to use for other things.

However, I've been doing more work on the command line recently, and not having ⌃A and ⌃E to move to the start and end of the current line was starting to grate. The cursor keys are just too far away!

So I whipped up some scripts to give me back those shortcuts while keeping the rest of the Emacs stuff disabled.

Start of line

set line_start to the characterOffset of line (startLine of the selection)
select insertion point before character line_start

End of line

set current_line to line (startLine of the selection)
set end_of_line to ((characterOffset of current_line) + (length of current_line))
select insertion point before character end_of_line

Wrap both of those in:

tell application "BBEdit"
    tell the front text window
        
    end
end

(omitted above to reduce the amount of scrolling), dump them in ~/Library/Application Support/BBEdit/Scripts/, assign them the ⌃A and ⌃E shortcuts in BBEdit's preferences, and you're all set.
