Rodin Editor User Guide

Introduction

The Rodin Editor plug-in provides a structured editor to model in Event-B withing Rodin. This editor uses a textual representation, and edition is done through an overlay text editor and action depending on the caret position in the text.

KEY SEQUENCE	ACTION
BACKSPACE (ENTER)	Enter the edition mode using the overlay editor if the caret is on an editable place.

Customize this list

If you don't like these shortcuts, you can modify them by setting your own key preferences. To do so, go to Window > Preferences and then General > Key. A table appears were you can find and edit the shortcuts.

Tips & Tricks

A command currently (i.e. in Rodin 2.2) disable the possibility to use the ESC instead of ALT+ESC sequence. This is quite cumbersome, and can be tuned! To do so, open the preference table for key shortcuts (described above) and after ensuring you disabled the filters of uncategorized commands (using the Filters... dialog) search for the command named "Restore Styles". This is the command to release the highlights in the proving views. You can then swith the sequence of this command to ALT+ESC and change the value of the "Abort edition and free selected items" command to ESC. After applying these settings, the shortcuts will be modified as wished above.
