You can use the slider bars to move your diagram up and down or left and right.You can use the + and - icons in the bottom right to make the diagram image bigger and smaller (zoom in and out).This looks like a circle with a dot in the center. You can center your diagram on the screen by clicking the 'center' icon in the bottom right.See 'Debugging' further down for information on using breakpoints.

В¶ BreakpointsД¬lick here to set a breakpoint. These are like Ctrl-Z and Ctrl-Y in Windows, which also work if you are inclined to using keyboard shortcuts. Use the 'undo' to fix a mistake, and 'redo' if you change your mind and want to reapply it. On the toolbar, you will see Undo and Redo buttons. The delete button in the top bar does the same. This will delete only the selected block, but not the ones underneath it.

Second method: click the block and press the 'Delete' key on your keyboard.

It can also be dragged back to the toolbox on the left side for the same effect.

This method will delete the block you selected plus all the other blocks connected below it in the diagram.

First method: click and drag the block to the trashcan icon in the bottom right corner of the programming area.

You can then Paste anything you cut or copied.

You can also click on a block and select 'Copy' which places a copy of the block on the clipboard so you can use a copy someplace else in your program.

Cut a single block out of a diagram without changing anything else by clicking on the block and clicking on the 'Cut' menu item.

These buttons (and other ways to accomplish their functions) are discussed in detail below.

If your block is on or very close to a compatible block, it will snap into place with an audible click, but if there is no click, they are not compatible.

Click on the block, and holding your mouse button down, grab and drag the block to a new location.

When you are pointing at a block the cursor arrow will turn to a hand.

This example shows Variable1 being set to a fixed value of 350.25, which is about to be clicked into the variable, and Variable2 set to the value of Variable1. Variables can be text, numbers, a Boolean, or a List. The Set block is used to set the value of a variable through the input notch. In our example below, the If Do block is accepting an input from a limit switch sensor called 'limit_a' and the value is either 'True' or 'False.' If Do blocks will be covered in more detail later. The input fits into the puzzle-piece opening on the right-hand edge of the block. Inputs can be variables, numbers, sensor values, controller inputs, or Boolean logical expressions. This is a basic block, which tells the robot's computer to do one thing, in this case to start the program and turn off the drivetrain:

There are a few things to know about blocks and how to use them. This block, for example, tells the robot's computer to set the left speed to a speed level equal to joystick Channel 3 from the remote control: It allows users to apply programming principles without having to worry about syntax.

Blockly uses interlocking graphical blocks to represent code concepts like commands, variables, logical expressions, loops, and more. Instead of writing text programming code, with Blockly you will drag-and-drop graphical code blocks into a work area. It's not a prerequisite, but you will get a faster start with Blockly if you are already familiar with the IDE Quick Start Guide. Before reading this you should read through the Project and IDE Quick Start Guide.
