Toggle Drawing Mode with CTRL + SHIFT!

Switch on Drawing Mode to begin creating annotations on top of your apps, anywhere on your screen!

When Drawing Mode is on, the button would be colored bright green.

Use Left Click to start annotating on your screen! During this time you cannot interact with your apps underneath the overlay. You can only click on or type on the apps under the overlay when Drawing Mode is OFF

To quickly switch between annotating on top of your apps and interacting with the apps below your screen, use CTRL + SHIFT (hold down CTRL then press SHIFT) to switch Drawing Mode between OFF and ON

Pen Brush (P)

Highlighter Brush (H)

Eraser Brush (E)

Select a brush to use for drawing! The selected brush will be highlighted blue even if Drawing Mode is not on.

Choose from your palette of colors!

Click the Color Palette button to view your available colors.

Click on one of the colors to select it for your brush!

Alternatively use the 1, 2, 3, ..., 0 keybinds to change colors very quickly.

Custom colors can be set in the Settings Menu.

The current color is saved even if LAT is closed and reopened.

Change brush size!

• Conveniently use your mouse scroll wheel while in Drawing Mode to increase and decrease your brush sizes.
• The brush size of every brush is saved individually.
• Brush sizes are saved even when LAT is closed and reopened.
• The brush outline shown while in Drawing Mode would also reflect the size of the current brush.

Quickly clear all your annotations!

• Use the Erase All button to quickly remove all the annotations on your screen!
• Alternatively, press the Delete key instead of clicking the button to get the same outcome. (Customisable in Settings)

Save a Screenshot with your annotations really quickly!

• Press the Save/Screenshot button anytime to very quickly take a snapshot of your screen together with the annotations!
• You could also use the PrintScreen keybind while Drawing Mode is ON to do this. (Customisable in Settings)
• The new screenshot would automatically be saved in your Downloads folder with the current timestamp as the filename.
• The LAT Toolbar would be hidden before the screenshot is taken so that it does not block your screen!
• Change the default save location of the screenshot in the Others Tab of the Settings Menu. (Coming Soon!)

Minimize the toolbar and use LAT's keyboard shortcuts to make fuller use of your screen while annotating!

• Press the Minimise button anytime to compact the toolbar into a small square that only contains a Maximize button.
• In this way, you can make use of LAT's keyboard shortcuts to quickly draw annotations without the LAT toolbar taking up any of your screen's real estate!
• The Maximize button would be colored Dark Green or Light Green corresponding to whether you are in Drawing Mode or not.
• Click the Maximise button to turn the LAT Toolbar back into the full sized version!


• EXTRA! Use the alternative CTRL + M keyboard shortcut instead of the Minimize button to FULLY hide the LAT Toolbar away from your screen. (Experimental!)

Automatically save annotations of your slides while presenting!

Currently only supported on Windows!

This feature helps you quickly and automatically save pictures of each slide with your fresh annotations on them while you are still presenting live.

• Toggle the Slideshow Recording button to ON to start Slideshow Recording Mode! (You can either click the Slideshow Recording button or use the "R" keybind, customisable in Settings)


• Turn it on when you begin your PowerPoint slideshow or when presenting any other kind of slide deck!
• While in Drawing Mode, if you press the Right Arrow key to go to the next slide, then LAT would automatically record the current slide.


• After your slideshow has ended, turn off Slideshow Recording and you will find a PDF file of your annotated slides, as well as compiled individual images of your slides complete with your annotations in your Downloads folder! (Being able to select the folder to save it in is coming in the future)

NOTE: If you want to skip saving a slide, turn off Drawing Mode before pressing the Right Arrow key and that slide would not be saved. The slides would automatically save only while Drawing Mode is on.
