Left and right arrow keys to switch slides. I recommend putting the project in fullscreen. UPDATED INFORMATION: The window manager can now support stamped windows. This allows for pen elements such as text written in pen. Rename the Stamp Window broadcast to "Stamp " followed by the window's name. Ignore the new "when I start as a clone" event that is shorter than the other one. That displays the clones according to if the window (or some other window) is a stamped window or not. Ignore the Stamp Window script too. That script is responsible for correctly converting the clone window to a stamped window. The Window Info list now contains info about each element arranged in {element name, costume, x, y, ghost, brightness, color} for each element in the list which is updated using the Update Elements block. This is used to transition from clone-based windows to stamped windows. To convert a window from a regular clone-based window to a stamped window, add the window's name to the Stamped Programs list. You can turn it back into a clone window by removing the name from the list. Use the ghost, brightness, and color variables to set the effects instead of the blocks themselves. This will ensure compatibility with stamping. Finally, copy the script located in the backdrop. This is used for checking if there are any stamped windows, and if there are, it converts all clone windows to stamped windows. If you need additional help, ask me in the comments.
