     - `☐ Frame` : indicate the current line by drawing a rectangle frame around the text of the current line, using the color defined by **Settings > Style Configurator > Global Styles > Current line background color** style's `Background colour`, and with the rectangle-line thickness defined by the **Width** slider
         - **Width**: slider is used to set the width (in pixels) for the lines of the rectangle Frame for the current line
     - (In v8.4 and earlier, this multi-control section was just listed as `☐ Enable current line highlighting` in the list of checkboxes, and was the equivalent of `☐` being **None** and ☑ being **Highlight Background**.)
+* `☐ Make current level folding/unfolding commands toggleable`: enables the feature that causes the [**View** menu]()'s **Collapse/Uncollapse Current Level** commands to both toggle the state of folding for the current level (so doing the command twice will undo the action); when not checkmarked, the **Collapse** will only cause the current level to fold, and **Uncollapse** will only cause the current level to unfold (new to v8.4.2)
 * `☐ Enable Multi-Editing`: allows multiple selections not necessarily contiguous with each other by using Ctrl+Mouse click on the selection(s) (was known as **Multi-Editing Settings** prior to v7.9.2)
 * `☐ Enable smooth font`: enables a font-smoothing algorithm from Windows, which may affect how smooth fonts are on some displays
 * `☐ Enable scrolling beyond last line`: allows you to scroll (with scroll bar or mouse wheel) so that up to a page of blank space _after_ the last line is visible.  (Disabled, scrolling to the end will put the last line of text as the bottom line in the window, when there are more lines of text than are visible in the window)
