Props make it easy to leave items on screen for an extended time, but are also easy to clear at any time. Some common uses for Props may be a lower-third graphic, a logo in the corner of the screen (sometimes called a “bug”), or other persistent graphic that you want to leave on screen.
A Prop can remain on screen for just one slide, multiple slides, or for as long as you want. This layer is independent of other layers allowing Props to be triggered at any moment. Props adhere to transparency settings for those graphic formats that support them (such as PNG files and animation videos with an alpha channel).
To open the Props window, customize the toolbar to add the Props icon, select it from the View menu, or use Control-P (Control-Shift-P on a PC) on your keyboard.
To activate a Prop, click on the Prop thumbnail. You can clear individual Props by clicking on the Prop’s name in the toolbar. If you want to clear all of the Props at once, add the Clear Props button to the toolbar and use that. (The Clear Props button is not included in the default toolbar.)
If you want to change the Props window to a floating window, click on the icon in the top-right corner. To return it to a docked position, click on the same corner again.
The first button in the lower-left corner is the Edit button. Clicking on this will open the Props Editor where you can create as many Props as you need. The second button allows you to set transitions for the Props. The slider in the lower-right corner changes the size of the thumbnails.
