Upon hitting record inside Camtasia recorder, you'll notice that there's a slight delay before it goes into its recording feature in minimises that's very minimal and usually about less than a quarter of a second. That's why most people use the countdown. When the Camtasia recorder is going, you can select it via this way manually, and choose to pause, stop or delete. Do note that your recorder and this function showing the menu will be displayed when you bring this up manually. Which is why I prefer and suggest using a hotkey in order to stop your recordings when you want to. Just like so.
Rather than being able to be driven behind having to pull it up from either this bar or inside of here and activating Camtasia to get it to stop hotkeys allow you to go on To fly, record instantly without having to click a button and then be able to move along as you need.
