	Orient elements horizontally to fit minimum bounding box. Shift+Click: Orient vertically. Right Click: Open Straighten settings. Iterations: Number of iterations to calculate the best rotation angle. Low values are faster to calculate, but precision may not be enough in some cases. Higher values calculates longer with higher precision.
	Rotate multiple elements by selected edges with automatic orientation. If edge is more horizontal than vertical, then element will be aligned horizontally. If no edges or vertices are selected then elements will be aligned by their longest open edges. Shift+Click: Force rotate to Vertical. Ctrl+Click: Force rotate to Horizontal.

Send selection Up the stack. Ctrl+Click: Search valid modifiers only below current modifier. Send selection Down the stack. Alt+Click: Don't search and send selection to new modifier. Can be combined with Shift/Ctrl. Righ Click: Open Transfer Selection dialog. Current modifier is marked by <<<. You can send selection to modifiers that marked by >>>. If current modifier is Unwrap, then you can send selection to Edit Poly and Editable Poly and vice versa. Create new modifier: Send selection to new modifier. Modifier will be added above selected item in list. Keep current selection: Transfered selection will be added to current selection.
UV <-> Poly	Create new object that represents object UV mapping on current Map Channel. Non-destructive Channel Info method is used here. All UV channels remain unaffected. This flat object could be used to deform it with Editable Poly tools and then send back to UV (read next). Ctrl+Click: Pick Poly object and use its geometry as UV mapping for selected object.

Open checkers folder	Open checkers folder in the Explorer.
Active Checkers	List of enabled Checker textures. You can disable unnecessary textures by deselecting them.

DLX status	UV Tools has C++ dlx extension which accelerate many functions. The script is fully functional without the extension, but those functions will run slower while dealing with many UV elements. Dlx extension should load on 3dsMax startup and can't be unloaded while 3dsMax is running. Therefore 3dsMax needs to be restarted if new dlx comes with the script update. DLX status field shows the current state of accelerator: Active: Dlx is loaded and used. Waiting for restart: Old dlx was disabled and new one is waiting for 3dsMax restart. Version mismatch: The script version doesn't match dlx version for some reason. Reinstall the script. Disabled manually: Dlx is succesfully loaded but disabled manually. Not loaded: Dlx is not loaded for some reason. Probably dlx accelerator is not compiled for your 3dsMax version at the moment.
Enable DLX Accelerator	Disable loaded dlx extension. Many UV Tools operations will run slower. Use only for dlx debug purposes.
DLX warning	Display warning message in statusbar when dlx is not active.
Open script folder	Open UV Tools script folder in the Explorer.

Due to constant script updates some of the functions shown in these videos can work different in the latest script version. Check Help section to find more actual information.
