Global search allows you search all documents in a workspace simultaneously.

### Getting started

Press Cmd-Shift-F or click in the search box on the toolbar to start a search. Once you have typed more than 2 characters of your search term, the search will start and a popover will appear with results as they are found. For a large document, this may take some time, especially when performing regex searches, and the results will be added as they are found.

## Regex Search

Some users may be familiar with Regular Expressions, often referred to as regexes. This is a special syntax for constructing complex text searches. This is not an introduction to Regular expressions, the Wikipedia page is a good place to start.

If you want to search by Regular Expression in Texpad, for example, the regular expression `string\s+theory`, type it into the search box enclosed in forward slashes, ie `/string\s+theory/`. Please note that applying complex regular expressions to a large document can take some time to return all results.

NB Texpad's Regular Expression engine is based on `icucore`, so it uses classical Unix syntax for Regular Expressions.

## Replacement

Once your results are displayed, you may want to replace some of them. To do this, type some replacement text in the box at the bottom of the search popover.

Select a result and press the `Replace` button to replace just that search result.

Press `Replace All` to replace all search results.

Please note that before any result is replaced, it will be compared to the original search term. It will only be replaced if it matches the original search term.

### Keyboard Navigation

The search window is designed to be fully navigable via the keyboard.

- Cmd-Shift-F: open the global search window
- Esc: close the global search popover without clearing it, this allows you to press Cmd-Shift-F to return to where you started.
- &#8593, &#8595: The up and down arrows let you navigate the global search results.
- Enter: Press enter on a global search result to close the window and jump to that result in the text.
