Editor

Automatically indent new lines
Will cause Hotpad to indent automatically when you start a new line.

Automatically align back braces
When you type }, Hotpad will look for the previous matching { and align the indentation with it.

Expand tabs to spaces
Will cause Hotpad to replace tabs with X spaces, including when opening files.

Allow blocktab
Allows you to select a block of text and indent the whole block using tab and shift-tab. Be careful not to hold down tab while you do this, or the editor may overwrite the text before it can apply the proper spacing.

Enable Hotpad undo
This enables undo using CTRL-`. The text area provided for your OS may already have limited undo using CTRL-Z, but this will enable multiple undos, up to the amount entered in the accompanying text field.
