To have a "global flap" from the flap menu check "shared by all projects" this can be used to "copy" objects between projects. You need to be careful that whatever objects you copy between projects are "self contained" (ie: do not refer to any other objects, that you do not copy, in any scripts).
Number lines allow you to have an alternate scale for the playfield they are in. For example drag a rectangle into playfield (the world, page in a book, holder or a playfield object) then open its viewer and look at the basic and graphing categories. You will see that "x" and "x on graph" are the same. Next drag in a "Horizontal Number line" (or Verical) and you will see the values for "x on graph change. You can change the "number line" using the number line category in its viewer.
The "X-Y plane" in the Graphing category of the Object Catolog provides a pre-gridded playfield (ctually Graph Paper) with X-Y axis. Get the "X-Y plane"s Halo and click on the Eye dropper to adjust the grid sizes. There are some issues when you adjust the grid sizes and move the Number Lines which I wish were "better integrated" and also the playfield's gridding (from the menu ==> playfield options) is not the same as the gridding used for the "graph paper" lines.
> Key press
Key press is used to deal with the problem of handling multiple key presses at the same time. This pops up for kids when they are trying to create multi-player games. Try using "last keystroke" from the input category for two or more keys then press both keys at the same time. Only the last one pressed wins. With Key Press you can detect multiple KeyPresses at the same time (limited I believe by the hardware). To change the key simply click in the white area and then "Press new key". Then to use in a script (with a Test block) go the the "Key Press" objects viewer ==> input category and use [key is pressed] tile. You can also detect how long a key is pressed as well (and reset that value to fire a message every n milli-seconds).
> Speech Bubbles
Way cool, you should check Ricardo's demo projects. These are similar to Scratch "Say/Think" tiles with the added benefit that they you can embed objects in them (which can also be scripted and thus have animated Speech and Though bubbles.
+1 Thanks for all your efforts. Keep up the good work!!!
