+## Browser tabs
+SaltGUI is a single page web-application.
+In cases where you would zoom in on details, it is possible to open a new browser tab with the requested details.
+Use CTRL-click to open the page in a new tab.
+Use ALT-click to open the page in a new tab and also make that the current tab.
+This works for clicks on table-rows and for clicks on popup-menu items.
+These functions are a bit browser-dependent, but all major browsers seem to follow this behavior.
+When a new tab is opened by SaltGUI, it does not contain a menu bar, secondary panels or a close-button inside the page.

 ## Command Box
 SaltGUI supports entry of commands using the "command-box". Click on `>_` in the top right corner to open it.
