Shift-Click-R is a feature in Scratch 1.x that allows Scratchers to access the Squeak workspace and do a variety of things, including editing the source code in the System Browser, re-gaining obsolete blocks, enabling Mesh or creating new blocks.
|Warning:||This is not recommended for beginners to Squeak. Changing settings by Shift-Click-R can change important settings and "break" your copy of Scratch. If this happens, reinstall Scratch. To be safe, edit the Source Code version of Scratch rather than the user version.|
Accessing the System Browser
- Hold and click the rounded bit of the R in the Scratch logo (look at the top left corner).
- Click "Turn fill screen off".
- Click the white area that appears at the right and bottom of the window.
- Click open....
- Click browser
- The System Browser appears — this is where one can edit the code.
Turn Error Catching Off
The "turn error catching off" option in the Shift-Click-R menu turns off the error catching, which turns a block red if there is something wrong with the input values, or if it can not execute the block for some other reason.
If a script error comes up, a red outline will appear:
That is with the error catching on. When off, this error debugger, or a similar error debugger, will appear instead of the script turning red:
Save Image for End-User
When the R is shift-clicked, it comes up with the option "save image for end-user." This saves any changes made to the IMAGE file in the user mode so that when it is opened, it will always open like the 'turn fill screen off' button. This feature is used in programming Scratch modifications to create the .image file.
|Warning:||Undoing the changes that you have made can be hard and sometimes impossible. If this occurs, simply reinstall Scratch.|
Shift-click-R before 1.4
Prior to Scratch 1.4, many other features could be found by using the "Set MIDI port" option. Experimental blocks and such could be viewed as well, but all this has been lost with Scratch 1.4's release — however, there are other ways to access those areas.
In Scratch 1.0, this menu was accessed by shift-clicking the "extras" menu.
