Search|Highlight All

After using Prepare to Search or pressing Ctrl+F and entering a search term, click the Highlight button on the search toolbar or select the Highlight All item in the Search menu to turn on the search match highlighting mode. In this mode, all search matches will be highlighted. The Selection Only option is ignored. You can configure the "highlighted search match" color in Options|Configure File Types|Colors.

When you switch between files, search matches in the newly activated line will be highlighted, regardless of the "all files" setting. To stop highlighting search matches, simply click the Highlight button again.
