-- <key>alt-p</key> to put videos in pip
-	- if multiple videos are found, you can pick which one to put in pip
-	- press again to unpip
+- <key>alt-p</key> to put videos in pip (picture in picture)
+	- if multiple videos are found, you can pick which one to put in pip - press again to unpip
 - hold alt to temporarily speed up videos 5x
+- automatic tab group collapsing (read note below)
+
+to make automatic tab group collapsing work, you need to hijack ctrl{-shift}-tab.
+you can do so by running the code on `chrome://extensions`
+
+```js
+chrome.developerPrivate.updateExtensionCommand({
+    extensionId: "<whatever id chrome chooses>", commandName: "nextTab",
+    keybinding: "Ctrl+Tab"
+});
+
+chrome.developerPrivate.updateExtensionCommand({
+    extensionId: "<the same id again>", commandName: "prevTab",
+    keybinding: "Ctrl+Shift+Tab"
+});
