Openbox: switch to Application nr #1, #2, ... on current workspace

[honeybear]

Hi,

I would like to set to shortcut:

windowsflagkey + 1,2,... to the first application of tint2, ... and so on.

You can do it with alt+tab ok, but I would like that window_key and 1,2,... key does it for me.

Any help would be appreciated since no idea how to manage it... :( no help on wiki

Kind regards
