In danmakufu , How do you focus ?  ?

Space bar - makes Danmakufu goes faster 

tab
z - shoot
x - bomb
c - nothing
v - nothing
b - nothing
n - nothing
m - nothing

  meh is it my keyboard? I've tried looking in the danmakufu help which is suppose to be a manual but it's all in gibberish 

 :V it's terrible without focus shot . . .

It is shift for focus...
Does your keyboard support more than three buttons pressed together?
