Hi,
at first, you posted your question to Visualization forum, but I guess it belongs to general MicroStation forum.
I am not quite sure what your problem is, but if your question is "How to enable navigation using keys", go to Preferences dialog (MicroStation menu > Workspace > Preferences...) and in category Position Mapping check whether "Use Position Mapping" is switched on.
With regards,
Jan

Hi Tham,
this is English forum, so please don't use Vietnamese, because it will confuse the most of reader.
[Edited] When it seems better to use local langauge, I guess it's better to send a message to the asking member.
Regards,
Jan is right. This question belongs to the MicroStation forum. the numbers 1-9 in the picture is known as "Keyboard Mapping" Adding to Jan's reply, here's the image for your reference.
