On the Colors and Syntax page in the file type configuration you can select a syntax coloring scheme for each file type. A syntax coloring scheme can apply case conversion rules to specific parts of the text. The HTML scheme included with EditPad, for example, specifies that HTML tags should be lowercase.
The Adjust Case item in the Case submenu of the Convert menu is only enabled when the syntax coloring scheme used for the active file specifies such case conversion rules. Click it to convert the selected text according to the scheme’s case conversion rules. If there is no selection, the command converts the case of the line that the cursor is on.
If you’d like this conversion to happen automatically as you enter text, turn on Convert|Case|Auto Adjust Case.
