Eng:Shift-Click-R

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.

Accessing the System Browser



 * 1) Hold shift and click the rounded bit of the R in the Scratch logo (look at the top left corner).
 * 2) Click "Turn fill screen off".
 * 3) Click the white area that appears at the right and bottom of the window.
 * 4) Click open....
 * 5) Click browser
 * 6) The System Browser appears this is where you 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.

What it does
If a script error comes up, you will get something like this:



That is with the error catching on. When off, this error, or a similar error, will appear instead of the script turning red:



Save Image for End-User
When you Shift-Click the R, 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 you open it, it will always open like the 'turn fill screen off' button. This feature is used in programming Scratch modifications to create the .image file.

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 however, there are other ways to access those areas.

In Scratch 1.0, this menu was accessed by shift-clicking the "extras" menu.

Alt-Click/ Command-Click
When one turns off the fill screen and holds down Alt on Windows, or ⌘ on Mac, and an area of the Scratch program is clicked, some icons show up. Clicking them pulls up certain menus and allows certain actions, like resizing a window.

Squeak Morph Examples


Under the 'new morph' category in the World Menu, there are many morphs which can be added to the Scratch GUI.
