I know it takes some time to get used to all this settings. But afterwards you probably will not miss this program.
AlReader - Full program help
Backlight intensity: Slide finger on left or right site up/down
Menu:
1) Slide Finger on the upper side of the screen from left to right or vice versa.
or
2) Tap in the middle of the screen
Number of profiles:
You will find it under:
Settings - Master ? (first option from the top) - number of profiles (number four is inverted screen)
If you don't find it, you have to set:
Settings - View settings - All features and settings
don't forget
Settings - Master - start with fullscreen
Settings - Master - dictionary
Settings -finetuning - Hardware - E-Ink refresh
Settings -finetuning - Fonts - Dev_Kern_Text
Settings -finetuning - Fonts - Linear_Text
Use the 10 Tapzones, if you want to use dictionary support, assign the tapzone only to shortclick and leave longclick for dictionary selection.
Have a look at the finger gestures, those could be useful too (I use it to switch between profile, change line-distance, letter distance ...)
