Is there a way to specify the rules for highlighting words and variables using - for example - Ctrl+D or double clicking a word?
What I mean is, if you have a variable like $example, double clicking this would highlight everything including its dollar symbol so you can copy/paste it without having to first type an additional dollar symbol.
The current behaviour is, if you double click $example, only "example" is highlighted and the dollar symbol is not.
Also, in the same vein, can you specify "smart highlighting" or "smart caret positioning" so that if you have a variable with underscores or camelCase, double clicking only highlights a certain part of the variable? For example: $example_with_underscores or $exampleWithCamelCase would only highlight "with" if I double-clicked on "_with_"? Then if I double clicked again, it would proceed to select the entire variable?
