I am using vim on a browser-based RDP session. Unfortunately, my browser is realllllly particular about capturing the "ctrl-w" key combo, because of unrelated-to-my-specific-use-case security reasons. This prevents me from using the pane feature of vim, because when I try to switch panes, my tab closes (!!!). Is there a way to change the "pane switch" hotkey to something besides "ctrl-w" in vim?
