You can insert more to your recording using the Insert New Recording tool to insert a new recording or the Insert Existing Recording tool to insert an existing recording. For example if we wanted to insert more at the end of this recording then we'd click at the end of the timeline then press the "Tools" button above the timeline then select "Insert" At that point you can choose if you want to insert a "New Recording" which will bring up the screen recorder so you can make a new recording. Or you can click on the "Existing Recording" option which will bring up a list of recordings on your computer so you can choose one to insert. Once you pick an existing recording or finish your new recording you'll be shown a prompt to make sure you are positioned at the right spot you want to insert at. If you aren't at the right spot you can drag the blue bar or use the arrow keys to seek on the timeline to where you want to insert. One more tip about positioning. If you click off the blue bar to find your spot, you can reposition the insert point to that spot by pressing the "S" key. To test your position, you can click the "Preview" button to see what the insert looks like when you transition into your insert. Once you are positioned in the right spot you can click OK or press the Enter key and your insert will be saved. Anytime you make a change to the recording it is automatically saved on your computer. After the insert is added a colored span will show on the timeline showing where the insert happened. If you want to later remove the insert you can seek back to that spot on the timeline then click this icon which will bring up a menu with another icon you can press to remove the insert. You can also use the undo or edit history drop down to go back in time before you added the edit if you'd like to remove it. The last used tool will be listed next to the Tools button above the timeline so you can easily use the same tool again by clicking on it here.
