When going to the search function within a document (for example through keystroke shortcut), the text of the last search is not automatically selected. For a new search, one must therefore do this manually with another keystroke (CMD + A), as otherwise the new search string is simply inserted behind the old/last one.

It would be ideal if Zotero would automatically select the text of the last search, just like most other programs do (Chrome for example). Then one can simply overwrite the old search term.
