 Link Action block
 ===========
-The Link Action block provides a user-friendly button that links to other Flows. 
-Like a normal link, the user can choose how Flows are opened, according to their browser configuration.
+The Link Action block provides a user-friendly button that links to other Flows.
 
-By default, links to Flows made with the Link Action block will open in the same window/tab context, but users with a mouse input device may right-click to open the link in a new tab or window, or on mobile devices with touchscreens, typically users would press and hold to open a Flow link produced by the Link Action block in a new tab.
-On supported browsers, users may notice the destination Flow is shown when hovering over the link, this allows the user to directly see where the button would navigate to.
+The block is implemented as a link and not a real button, and benefits from the usual behaviour of browser links, for example, the user can choose how Flows are opened, such as the same in the same tab, or a new tab, based on their browser configuration, and users may notice the destination Flow is shown when hovering over the link, this allows the user to directly see where the button would navigate to (which is an improvement over the Launch block, see below).
