Here is one of my favorites TBS features, you can select a range of cells and by using one command element>cell> set exposure to "X" (where X is a number of your choice) you can add "X" number of exposure frames between each of the cells in your original selection. This is great for changing a sequence from 1's to 2's or 3's for timing.

When you view the drawings contained in an element (a column) on the exposure sheet, you will see a drawing title (a row) which is connected to a frame number and in many cases there may be a sequence of repeated exposures of that drawing spanning a series of frames. I like to refer to this sequence of repeated exposures of a single drawing as an exposure set. You control the amount of time that a drawing is seen on the screen by setting the number of frames in its exposure set. Setting exposures is fundamental to animation timing.

Adjusting Animation Timing With Set Exposure
You always want to extend exposures from the first frame of the sequence of frames in an exposure set. For example, you have a drawing titled c-12 at frame 23 and you want to extend its exposure for 3 frames. You select c-12 at frame 23 and you <right click> and choose set exposure to 3. This adds 2 additional exposure frames of drawing c-12. Suppose that you want to change your timing and set the number of exposures of c-12 to 4 exposures instead. You go back to frame 23, in this example, and select just drawing cell c-12 again and <right click> and choose set exposure. This opens a dialog panel where you will enter 4 in the “frames” text box and click OK. You now will have 4 exposure frames of c-12 instead of 3. Suppose you don't like that timing and you really wanted it to only be 2 exposure frames. You need to go back to frame 23 ,again, and select drawing c-12 and this time <right click> and choose set exposure to 2 .This reduces the exposure frames for drawing c-12 from 4 to 2. You can add or subtract exposures using this technique as a way to adjust and fine tune your animation timing.

This technique also works on the timeline. You select the desired drawing which is represented by a tick mark on the track for the element and <right click> and choose set exposure and enter the desired total number of frame exposures in the dialog panel.
