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.
For more details about the principles of this editor, see the Rodin Editor Plug-in page.

Using keyboard shorcuts
Here is the list of the currently key bindings which are set by default and specific to the Rodin Editor.
| KEY SEQUENCE | ACTION |
|---|---|
| BACKSPACE (ENTER) | Enter the edition mode using the overlay editor if the caret is on an editable place. |
| DEL | Suppress the element after the caret position |
| CTRL+T | Add a sibling of the element pointed by the caret position. The sibling is placed just after this latter one. |
| CTRL+SHIFT+N | Opens a popup to select the element type of the child to add to the element pointed by the caret position. Note that if there is only one child type, the child will be directly created. |
| CTRL+BACKSPACE | Insert a new carriage return while editing with the overlay editor. |
| ALT+ARROW_UP | Move up the selected elements. |
| ALT+ARROW_DOWN | Move down the selected elements. |
| SHIFT+ARROW_UP | Select elements up. |
| SHIFT+ARROW_DOWN | Select elements down. |
| ALT+ESC | Quit the current overlay edition (if any) and forget the modifications made, frees the current selection. |
| TAB | Go to the next editable place (i.e. to the next editable element attribute) |
| SHIFT+TAB | Go to the previous editable place (i.e. to the next editable element attribute) |
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.
