extradev: Navigate in 2D + Multiplication Sign and some CJK punctuations

[jesus2099]

• Navigate in 2D with +up+ right +down+ left arrows
• Add Multiplication Sign, Wave Dash and Corner Brackets

Apparently, the default item is not possible in other languages than first found.

CJK category (not 1 country) may make your script going in weird direction.

I think I need to make it better, as can be discussed in the forum.

I did what I said in the forum:

• Use Japanese with Japan flag instead of CJK
• Group related characters (math)
