The KeyBar is a section of the Framebar that shows the keys pressed in any frame.
Viewing modes
There are two ways that the KeyBar can show key press data: "Raw", which shows all key presses in a sequence and "Sentence" which groups together presses into words and lines, and is more easily readable.
Here is an example of the same word ("test") typed during the movie and viewed in Raw then Sentence mode.
In Raw mode it looks like this:
You can see the frame in which each of the letters was pressed.
In sentence mode, the key presses are grouped together into a word, and the KeyBar shaded in blue to show the duration of the word:
So Raw mode gives a more 'detailed' view of the key presses, but Sentence mode is easier to understand.
More on sentence mode
Sentence mode attempts to simplify the display by showing you the results of edits and corrections. For example, if a user mistyped "Treasure" as :
Treasire
And then corrected the word by hitting backspace three times and retyping "ure", you would see in the Key logging window, in Sentence mode:
Treasure
BB FlashBack Express has combined the key presses together. However, it can only do this for simple cases, where the backspace, arrow and delete keys are used.
More on Raw mode
Where there is more than one key pressed in a single frame, Raw mode draws the frame with a small green indicator. To see all the key presses in the frame, put the mouse over the frame to show its thumbnail image. The keys are listed under the image.
In the example below, the 't' and 'e' keys were pressed in the same frame. I put the mouse over the frame to see the thumbnail:
Virtual keys
In both Raw and Sentence views, virtual keys such as arrow keys, modifier keys (e.g. Ctrl or Alt) and function keys are shown in blue. In the example above, the small blue triangle shows when the space key was pressed.
Here is a list of virtual keys and how BB FlashBack Express represents them in the KeyBar:
