I play with keybord and mouse
when i press Tab to access to inventory, I cannot navigate between page of inventory, the supposed key "1", "2", "3", "4" doesn't work with numpad, or capslock and shift.

So i could only access to first page when i open it by pressing "Tab" and map page by pressing "M"
but the to other page is health condition and document.
Does it locked at the beginning?

I play on french keyboard, so i change key for direction but it doesn't have effect on the control in the inventory.
I tried try all control on keyboard, nothing give me access to the page of stats and document

Could you help me?

Although many time had passed, I tried it now and can confirm it. Problem is, that later in game is necessary (in first save room) pass ID chip, which needs pressing key "3" which is not working, so this game is broken. I tried even change keys, but it did not help. Either way I will not buy second game from the series as such bug should be already fixed.
