When you type the start of an identifier and press the Escape key, Wedit will try to find the closest match to the incomplete identifier. If only one match is found, it will be inserted without further questions. If multiple matches are found, you will be presented with a contextual menu with those identifiers or with a dialog box if the number of identifiers found is too great to be presented in a menu.
If you press Escape after having written an identifier followed by a point or a sequence of ‘->’ characters, Wedit will try to find the fields of the structure you are writing.
Wedit tracks the include files to search for identifiers. Comments will be ignored, but conditional definitions will not be executed because for this, the preprocessor would have to run.
