Hello,

YES.. you can use MS Paint without mouse also.

This is a little bit difficult but you can still use it if necessary.

Click ALT key and use your arrow keys to toggle and to select buttons/icons in the tool bar.

To draw with a pen, you can hold the space bar and use the arrow keys to move the cursor in the required direction.

You can watch tutorial videos on Youtube for more information and clarity on the same.

Hope this helps.

Thanks.
