To hide the cursor or webcam over a section of your recording you would first seek to where you want to start hiding. Then you would click the "Tools" menu button above the timeline and then "Hide" and then choose either "Cursor" or "Webcam". Or you can just press the "H" key then the "C" or "W" key to start the tool. Select the section by dragging the orange bar along the timeline or if you click on the start or end of the span then you can use the arrow keys to fine tune your selection. You can also click around the timeline then use the "S" key to jump the start to that point or the "E" key to jump the end to your current seek point. If you want to Preview what it will look like then you can press the Preview button which will seek right before the section then play through it and stop shortly after the section. Once you're ready to commit you press the OK button or press enter. Anytime you make a change to the recording it is automatically saved on your computer. After the edit is added a colored span will show on the timeline where you added the hide. If you want to undo it then you can seek back to that spot on the timeline and click this icon which will bring up a menu with another icon you can press to remove it or you can adjust the seciton by dragging the ends. 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.
