+## Keyboard Shortcuts
 The default keyboard shortcuts are based on Spectacle, but there is a recommended alternative set of defaults based on the Magnet app. This can be enabled by setting "alternateDefaultShortcuts" to true in NSUserDefaults for Rectangle with the following Terminal command:
 
 `defaults write com.knollsoft.Rectangle alternateDefaultShortcuts -bool true`
 
-Then restart the Rectangle app.

+## Differences with Spectacle
 Spectacle used its own keyboard shortcut recorder, while Rectangle uses [MASShortcut](https://github.com/shpakovski/MASShortcut), a well maintained open source library for shortcut recording in macOS apps. This cuts down dramatically on the number of bugs that were only in Spectacle because of the custom shortcut recorder.

 * There's an option to have windows traverse across displays on subsequent left or right executions, similar to what Microsoft provided in Windows 7.
 * Windows will snap when dragged to edges/corners of the screen. This can be disabled.
 
+### Details on halves to thirds (subsequent execution of half and quarter actions)
+The default behavior for Rectangle is based on Spectacle. Each time you execute a half or quarter action, the width of the window will cycle through the following sizes: 1/2 -> 2/3 -> 1/3.
+
+This behavior can be disabled with the following terminal command:
+
+`defaults write com.knollsoft.Rectangle subsequentExecutionMode -int 2`
+
+Followed by a restart of the app.
+
+Note that the `subsequentExecutionMode` is also tied to the setting for traversing displays in the prefs.
