There is no shortcut key of input in qbasic

the extensions of qbasic are that, there are only 80 pixels to write in the qbasic
qbasic is important because its technology

Qbasic and Quickbasic are not the same! Qbasic was a free interpreter that Microsoft included with MS-DOS. Although Quickbasic uses similar syntax as quickbasic it allows programs to be compiled.

The advantage of qbasic is that it is easy to learn, to start out,then one can move on to more complex, or advanced languages.
