What went wrong?

When viewing a PDF and using the find option, certain characters are not accepted.

• b, f (switches to fullscreen), m, s, t

The uppercase versions do work.

Steps to reproduce

1. View PDF
2. Select search/find option in top write
3. Type "bfmst"

Expected vs actual behavior

When search/find textbox is focused all characters should be acceptable
