+Mouse support
+=============
+
+With this patch dmenu will have basic mouse support. The following features are supported:
+
+Mouse actions supported:
+
+* Left-mouse click:
+ * On prompt and input field: clear input text and selection.
+ * In horizontal and vertical mode on item: select and output item (same as pressing enter).
+ * In horizontal mode on arrows: change items to show left or right.
+* Right-mouse click: close.
+* Middle-mouse click:
+ * Paste current selection.
+ * While holding shift: paste primary selection.
+* Scroll up:
+ * In horizontal mode: same as left-clicking on left arrow.
+ * In vertical mode: show items above.
+* Scroll down:
+ * In horizontal mode: same as left-clicking on right arrow.
+ * In vertical mode: show items below.
+
+The attached patch applies cleanly to latest dmenu 4.5 tip (dec9a28863f388072be105e0950deb72ac719d48).
