Hmm... never really noticed that, but maybe it's because I do basic operations and in Keynote there are multiple ways to configure/perform a search:Stef123 wrote: the only downside seems to be the Search function which has weird quirks and glitches.
1) Ctrl+F open a box where you can select some options (especially 'From top', 'Search all notes' and 'Search all tree nodes'); forget one of them and you'll end up with partial results.
2) Tab 'Find' in the Resource panel (F9) presents different configurations, and the results are neatly displayed in a list. Double click on one of them goes to the choosen entry.
Nonetheless, it's a basic search; I often would have liked to perform a single content search over multiple files (while just one is open), but alas... it's not possible.
