+### Going to / Opening / Previewing Result Location
 When the cursor is placed on a result file path, you can go to that file by pressing `<enter>` in normal mode (`Goto` action default keybind).
 When it's placed over a result match line, you will be taken to the file/line/column of the match. By default, the file buffer
 is opened in the last window you were in before opening grug-far, which is typically the other vertical split.
@@ -156,6 +156,8 @@ _Note:_ for both `Goto` and `Open` actions, if a `<count>` is entered beforehand
 
 In order to smoothly `Open` each result location in sequence, you can use the `Open Next` and `Open Prev` actions.
 
+If you would like to keep the buffers layout, you can use the `Preview` action instead, which will open location in a floating window.

 ### Opening result lines in quickfix list
 
 Result lines can be opened in the quickfix list. Deleting result lines will cause them not to be included.
