<cword> is replaced with the word under the cursor (like |star|)
<cWORD> is replaced with the WORD under the cursor (see |WORD|)
+ <cexpr> is replaced with the word under the cursor, including more
+ to form a C expression. E.g., when the cursor is on "arg"
+ of "ptr->arg" then the result is "ptr->arg"; when the
+ cursor is on "]" of "list[idx]" then the result is
+ "list[idx]". This is used for |v:beval_text|.
<cfile> is replaced with the path name under the cursor (like what
|gf| uses)
<afile> When executing autocommands, is replaced with the file name
