R: changes the ordering. If it's light, it displays the images randomly, if it's dark, it walks through them in order.
T: restarts the timer with the current image (basically the same as moving left and then right).
Left arrow: jumps back to the previous image (if it can: check the "Image history" section).
Timer circle: pauses and resumes the timer.
Right arrow: gets the next image (either randomly or not).
F: displays a folder selection dialog. If there is a folder selected, it clears the image history, restarts the timer, and displays either the first image, or a random one.
(Note: the OS can mess up some default folder localization names ("My pictures", etc), so in order to avoid errors, don't choose them.)
S: displays the settings window.

helpText6 = """Session seconds: the length of each drawing session. Lower limit is 1, upper limit is technically nonexistent (except the memory limitations), but please try to end it before the heat death of the universe...
Break seconds: the option to include a short (or long, you decide) break between sessions. Lower limit is 0, in which case it will simply goes to the next image without hesitation.
Image history size: the program keeps track of the last x images for two reasons: to enable left scrolling, and to not randomly select the images in it (thus eliminating repetition). A size of 50 should be enough for all purposes, but it can handle larger without a problem. Also, the history size cannot be bigger than the number of images in the directory.


Note: hitting Enter saves the inputs (just like clicking the Save button), hitting Esc closes the settings window (without saving).
Another note: if you want to delete the saved config data, delete config.txt from the folder of the program."""
