Remember to read the Conditions of Use, Publication and Distribution before installing and using our Applications.

3. How to install it?
No particular installation is required. Once you've downloaded the ".dmg" package from our website, it should uncompress automatically (in your "Downloads" folder or on your Desktop). If it does not, then you can double-click on it to uncompress it.
Then you just have to move the created folder into your "Applications" folder (or any other location) and double-click on the Application to launch it.

Particular case of MacOS 11 Big Sur:

Under MacOS 11 Big Sur, if you're launching the Application for the first time, MacOS' GateKeeper (which you can configure in the "System Preferences") will refuse to launch it because you've not downloaded it from the Mac App Store (but from our website). In this case, instead of double-clicking on it, all you have to do is to right-click on the Application's icon, and then select the "Open" menu. A message will appear in which you'll be able to confirm that you want to launch the Application (even if it was not downloaded from the Mac App Store from an Identified Developper).

NB: We're not distributing our Applications through the Mac App Store, because Apple's fees policy on the Mac App Store is not financially respectful of developers and small and medium companies, and consequently, at the end, of customers.

4. How to uninstall it?
There should be no reason to do this. ;-)
However, if you really want, then you just have to throw the Application into the trash, and that's all.

5. How to use it?
The "File/Next window" menu:
It allows you to scroll to the next window.

The "File/Previous window" menu:
It allows you to scroll to the previous window.

The "File/Save and view with default application" menu:
It allows you to save and open the document with its default application, such as your web browser for an HTML file for example.

The "File/Reload from disk" menu:
It allows you to reload the current document from disk. All the changes you've made since you saved the document for the last time or since you opened it will be discarded.

The "Edit/Find and replace..." menu:
It allows you to find and replace text.

The "Edit/Regular expressions..." menu:
It allows you to find and replace text with regular expressions.
It is much more powerful than the simple find and replace function. It allows to search for complex expressions thanks to pattern matching and to replace them with other expressions thanks to pattern matching too, which can depend on the result of the search...
Many websites can teach you how to use regular expressions.

The "Edit/Toggle wrapping" menu:
It allows you to switch between wrapped text and unwrapped text in the current window.

The "Edit/Change ends of lines" menu:
It allows you to swap between Macintosh, Windows and Unix ends of lines.
