The HT1075 remote control is very reasonably laid out. The backlight is bright red, which I think is too bright in a fully darkened room, but not too bad. I've been less happy with some Optoma remotes which have an even brighter, but blue backlight.
Let's start at the top left with the Power switch (green). Next over is a smaller red button for power off. The backlight button is on the top far right.
Only four of the six buttons on next two rows work with this projector. 3D toggles 3D on and off (assuming a 3D source). Next over is PIP which does not work because the HT1075 does not have Picture in Picture. Below that is Swap, which also relates to PIP so also has no use. Auto (right side), is auto sync, primarily for analog computer sources. Invert (2nd row) flips the 3D glasses left and right eyes, when you need it to. The bottom right of those six buttons is labeled Eco Blank. Engage that to black the screen, and I believe you will save 70% of energy usage when engaged.
Moving right along, next comes the navigation area. Four arrow keys in a round formation with an center OK (enter) button. Below are three buttons - Back on the left, (oft called Escape) to move you back up a level in the menus, the Menu button itself, and the unrelated Source button. Pressing the Source button brings up your various sources, and then you use the navigation arrows and the OK button to select the source you want. (The projector also has an Auto source function so that it will find the next working source.)
The next three rows each have a rocker bar with three positions. The first one is for audio, with the left side being mute, pressing the center lowers volume, and the right side raises it.
The next two rows have "player" functionality. Forwarda and back chapters to the outside, with Play and Pause toggling in the center. Below them, Fast Rewind, Stop, and Fast Forward.
The remaining three rows of three buttons are all shortcuts to menu features. The first row offers Keytone correction, Color Mode (Cinema, Standard, User, etc.), and Brightness
The next row serves up Contrast, Color Temp, and Color Temp adjustments (Gain and Offset)
The last row: Gamma adjustment, the CMS (color management system) for calibrating the individual colors, and finally, Sharpness control.
Overall range of the remote control is pretty good. 20 feet with a bounce off the the screen is not a challenge for its range, which is good for a projector remote running on a pair of AAA batteries (many use AA batteries which have more power).
