Search in book - newbie question


I just installed Sumatra PDF … when I open the application from the start menu, there is a white banner across the top with a pulldown menu on the top left (File, View, Go to, etc.). Below that is a standard menu bar including Open document, print, a page number field … and towards the right, a search box.

However, when I open an epub file, this standard menu line disappears. I still have the pull down menu icon (three horizontal bars) beside the name of the open file, but the menu line with the open, print, prev page, next page, etc. - including the search box - has disappeared.

When I try to search in the open file (F3 or Ctrl-F), nothing happens. How do I search in an open book?



in settings > advanced options there is a section such as

EbookUI [
FontName = Georgia
FontSize = 12.5
TextColor = #5f4b32
BackgroundColor = #fbf0d9
UseFixedPageUI = false

change to

UseFixedPageUI = true

Don’t forget to save the changed settings file for it to be registered then close the ebook and reopen it
now you will have the same “Fixed page” User Interface as used for other formats, NOTE it will no longer appear as a “Dynamic Page” (reflowing etc)

like this


Thanks … that did it (though I’m surprised that this hasn’t been a more frequent question, and the solution a little more user-friendly).


agreed it would be best as a quick button / key-in or in standard options
however @kjk has strong views on a maximising canvas / minimising “clutter” since everyone wants different options visible

Implementation of search, copy etc. functionality in EbookUI has been requested many, many times, on the old forum as well as on GitHub. Just a few issues that I found with a quick search; quite likely there are more:

Copy/(paste) in epub
