I think a program would likely have lots of key words and most of it may end up being bolded. But what about bolding keywords that form blocks when the cursor is on one of the components? And similarly for brackets/parentheses/lists. In most programming editors, one can place a cursor on a delimiter and it will highlight the paired symbols. In this case, we could use bold. Similarly, if someone places a cursor on an IF THEN END block, then the key words "IF" "THEN" and "END" could be bolded (or even the entire block itself) until the cursor is moved out of the block. Or since we have greyscale, leave the font as is and just change the background to a light grey. This would allow a bold font to be used by the user without causing confusion with bold having some other meaning.

This kind of bolding will work efficiently only with the depth of 1, not when there is ie. depth of 3 or 13 of IF structures etc.
