Preferences: Exeptions of Methods
Here you are able to edit some context menu items that will appear when
right clicking while setting the throws of a method. In the context menu
you find the item "Reset on default values" that rebuilds the the list
to its original state.

By pressing "OK" you confirm changes, "Cancel" deletes any changes.
Some made changes can only be applied after restarting Jedi because
already used context menues can not be changed immediately.
