I should say at the moment I'm jut using wildcards, specifically (eg Issuer):
"[A-Z][a-z]{3,} Issuer" [not highlight] - to see if preceded by u/c word (having already highlighted all u/c words at beginning of paras (by highlighting wildcard 13^[A-Z]) and sentences (by highlighting all instances of '. ^$' and '. ^$')
and
"Issuer [A-Z]" to see if followed by u/c word.
Time-consuming!
