How can I change a word (that occurs often) in the document all at once

Question

I wanted to know if there is a key combination in Overleaf to change a word that occurs often in the document. Is there a possibility to change it all at once?

For Example

Lorem ipsum dolor sit amet Soerren, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam Soerren. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum Soerren sit amet.

I try to change Soerren into Sören

Lorem ipsum dolor sit amet Sören, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam Sören. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum Sören sit amet.

Answer 1

Press Ctrl+F when you edit your document on Overleaf. This opens the search-and-replace dialogue window at the top right.

To ensure that you only replace "Soeren" and not "Soerensen", press the third button on the bottom of that window (it looks like "...", highlighted in pink in the screenshot). (If you like you can also toggle on case sensitive search with the Aa button and/or use regular expressions.)

You can replace all words at once if you then click "All". I'm always a bit careful and go through at least some of the matches to make sure they look OK before I hit the "All" button.

See also the Overleaf help page about searching and replacing and the help page about regular expressions.
