No need for an extra script in this case.  You can just do:

    extendsyntax c linter cat found_tags

>   bind M-1 "^][1;5D^[a^[[1;5C^[6^R^Xgrep ^U tags > found_tags^M^T" main

I've changed this to:

   bind M-J "^[OC^[od^[A^[oc^[6^R^Xgrep ^U tags >found_tags^M^Ty^C" main

It uses the shortest available escape sequences for the arrow keys,
adds a <Right> at the beginning so the <Ctrl+Left> will do the right
thing when the cursor was on the first character of the symbol, adds
"y" at the end in case the symbol is in an unopened file, and finishes
with ^C to get out of the linter.

For a usable tags file, I need to run:

    ctags -x src/*.[ch] | awk '{print $3":"$2": "$1}'> tags
