# Touch Develop Editor
|
|
|
|
The Touch Develop editor.
|
|
|
|
### @parent js/contents
|
|
|
|
|
|
The Touch Develop editor is where you write and test your code. If you're new to Touch Develop, check out the [Touch Develop editor video](/getting-started/touchdevelop-editor).
|
|
|
|
To create a new Touch Develop script:
|
|
|
|
1. Go to the micro:bit website and click **Create Code** (along the top).
|
|
|
|
2. Under the Touch Develop editor heading, click **New project**.
|
|
|
|
3. Type a name for your script and click **create**.
|
|
|
|
An empty script with a [function](/js/function) called `main` is created.
|
|
|
|
## The Editor Menu Bar
|
|
|
|
The Touch Develop editor has a bar of options above the code area:
|
|
|
|
|
|
|
|
* `my scripts` takes you back to a list of your scripts (My Scripts). The open script is automatically saved (in the cloud) when you leave the editor.
|
|
* `run` executes your script, showing you the results on the on-screen micro:bit device. See [run scripts in the browser](/js/simulator) for more about this.
|
|
* `compile` sends your script to an ARM compiler, which creates a file that you can run on your micro:bit. See [run scripts on your micro:bit](/device/usb) for more info.
|
|
* `undo` undoes changes that you made to your script.
|
|
* `search code...` search for functions in libraries such as the micro:bit library.
|
|
* `script` opens script options, where you can do things like publish and preview. See **script options** below.
|
|
|
|
Many of the above buttons aren't much use until you've written some code, so let's move on to the Code Keyboard.
|
|
|
|
## Code Keyboard
|
|
|
|
The Code Keyboard makes it easy to write code on a touch screen device or by using your mouse. You can also type code using your computer keyboard if you know what function or statement you want (see [Touch Develop documentation](/js/contents) for a complete list).
|
|
|
|
To open the Code Keyboard, click on a line of code:
|
|
|
|
|
|
|
|
An on-screen keyboard appears, with buttons that vary depending on what's selected.
|
|
|
|
### Statements
|
|
|
|
The first row of the Code Keyboard has Touch Develop [statements](/js/statements) that you can insert into your code. These buttons are blue and include things like [var](/reference/variables/var), [if](/reference/logic/if), [for](/reference/loops/for) , and [while](/js/while). Click `more` to see additional statements.
|
|
|
|
### The BBC micro:bit, math, and code buttons
|
|
|
|
* `micro:bit`: click to see all the [micro:bit functions](/js/contents); click `more` to scroll left to right. The micro:bit functions are also grouped together behind the following category buttons: `basic`, `control`, `input`, `image`, `led`, and`pins`
|
|
* `code`: click to access functions you've written (see [call a function](/js/call) for more info)
|
|
* `math`: click to see [math functions](/js/math); such as `abs` and `round`
|
|
* `bits`: click to see functions for bit-level manipulation of integers
|
|
|
|
### Editing code: add, copy, paste, and cut
|
|
|
|
In the coding area...
|
|
|
|
* **add**: to add a new line, click on a line and then click a **+** to add a new line above or below the current line
|
|
* **copy, paste, cut**: click on a line then click **copy** or **cut**. Then click on a new line, and click **paste**.
|
|
|
|
### Block editing
|
|
|
|
To copy, cut, or comment out a block of code (more than one line):
|
|
|
|
1. Click on a line of code.
|
|
|
|
2. Press and hold the `Shift` key, and then press the `Up arrow` or `Down arrow` key on your keyboard (this selects multiple lines).
|
|
|
|
3. Choose a block editing option like copy, cut, or [comment out](/js/comment).

|
|
