The vertical selection editing feature allows you to replace similar lines quickly without using regular expressions.
For instance, you have a file with the following text:
Now you want to capitalize name1 to name4. Click the left of name1, and select all n's vertically while pressing ALT (or press CTRL + SHIFT + F8, and press RIGHT once, and press DOWN four times).
While all four n's are selected, enter N.
You see all n's have been replaced with N's.
