To add a bookmark in Google Chrome or Edge, simply navigate to the site you wish to bookmark and press CTRL and D together and you will see in the top right that the page you are on has been bookmarked.
The bookmark bar can be toggled by pressing CTRL, Shift and B so that it is always visible on every page or only visible on new tabs.
Bookmarks can be rearranged and edited in the bookmark manager, accessed by pressing CTRL, Shift and O.
Bookmarks are synced across supported devices if you are signed into Chrome with a Google Account or Edge with a Microsoft Account.
