Can drag blocks off pallette

[tonyforster]

Click a block on the pallette (do not drag) then press the cursor keys or H J K L, can drag the blocks off the pallette.

Presumably this is a buggy side effect of intentional block and stack keyboard shortcuts? If so, it should be documented in the wiki? Why also H J K L? Is it a useful shortcut if you still need the mouse to select them?

Also in the process managed to create some phantom blocks on the canvas (real blocks not pallette creators) which give errors if you try to drag them:

This patch excludes the proto blocks on the palette from being moved using the keyboard commands.

Why also H J K L? Is it a useful shortcut if you still need the mouse to select them?

To be implemented is to select a block by tabbing through all visible blocks. But regardless, it is sometimes more convenient to fine-tune the position of a block using the keyboard, especially when using a jumpy touchpad.

This patch will be included in v100. Meanwhile, testing would be appreciated.

Is the full list of keyboard shortcuts:

Alt+ palette; blocks; run; walk; stop; erase; e.g., Alt+e will erase the screen.
Esc will return from full-screen mode
ctrl c ctrl v
cursor keys H J K L
tab (when implemented)

?

Seems you need to have done a query keyboard block to get the bug?

I did a bit more updating of the documentation in the wiki and made the behavior more consistent. For example, you can move any turtle, not just turtle 1, and the selected block that is being moved is highlighted and undocked before moving.
