Hi Paul,

please try Regular Expression, like

Find: john.+?\b
Replace: tim
[X] Regular Expression

Explanation:
. (dot) >> match an single sign
+ >> match one-or-more of the expression just before (here: the dot)
? >> here: match non-greedy (only as much as need) . (depends which editor and which settings you use)
\b >> match till an space is found
