I have three little tips regarding editing expressions that I’d like to share today.
- You can adjust the size of the editing window by dragging its lower-right-hand corner. If you are trying to work with longer, more complicated expressions, this can be important, as the default window is quite small.
Using returns to change lines does not affect the validity of expressions. So, as I have done in the example shown above, line changes can help make the editing process easier.
A good text editor can be useful. On my Mac, I use a free app called TextWrangler. It’s the free version of BBEdit. One thing I like about it is that it helps me check how the parentheses are paired. If I use my arrow key to move the cursor over a closing parenthesis, it highlights the opening parenthesis with which it is paired. This helps me avoid parsing errors that result from having extra or missing parentheses.
