Customize Schemes

Select Scheme

Click menu "Schemes" -> "Select Scheme..." or "Select Scheme" toolbar button.

Favorite Schemes

Click menu "Schemes" -> "Favorite Schemes...".

When "Auto-select by filename extension." is enabled, filename extension is matched in following order:

1. Text File
2. 2nd Text File
3. Favorite schemes, in the order configured on this dialog
4. Other general schemes, in alphabetical order (case insensitive)

Because Notepad2 supports many schemes, some of them you may never use, it's better to select your own favorite schemes (maximum 31). You can click checkbox before each scheme to add or remove it from Favorite Schemes.

Drag & drop is supported on scheme tree, you can drag schemes into Favorite Schemes, or reorder existing favorite schemes by drag & drop.

Customize Schemes

Click menu "Schemes" -> "Customize Schemes..." or "Customize Schemes" toolbar button.

Drag & drop is supported on scheme tree, you can copy style settings to other styles by drag & drop.
