+### Description
+
+This patch adds an ability to add or change client rules at runtime.
+
+The patch only adds one keybinding (`Alt+Shift+R`) to toggle `isfloating`
+option, but this can be easily extended if you want to tweak other options as
+well. You just need to define a new function similar to `setruleisfloating` and
+add a new keybinding to `config.h`.
+
+For example, this is a function I created for my build to toggle `noswallow`
+option from the [swallow][swallow] patch:
+
+```c
+void
+setrulenoswallow(const Arg *arg) {
+	Rule *r = getrule(focustop(selmon));
+	if (!r)
+		return;
+	r->noswallow = !r->noswallow;
+}
+```
