How to get my terminal to open NeoVim with maximised window size using Openbox rc.xml key bindings?

I am using Openbox 3.6.1 windowing with Arch 5.6.4, and NeoVim 0.4.3, with gnome-terminal 3.36.1. These are the most up to date versions. I am currently sizing my gnome-terminal window using these lines within my NeoVim .vimrc file set lines=36 columns=128 However this is not ideal becasue I frequently have different window layout needs. What I want is for the window to open maximised, whatever my windowing layout. On the gnome-terminal command line, the following command opens file rc.xml with nvim in the gnome-terminal, with maximised window as expected. gnome-terminal --window --maximize -e "bash -c 'nvim /home/user/rc.xml'" I dont usually open files with nvim this way though. What I do is I call nvim in gnome terminal, using an Openbox key binding. Here are 3 example key bindings I have tried within the rc.xml file .. .. this keybinding opens the rc.xml file with nvim, but not with the maximised gnome-terminal window as needed ... gnome-terminal --window --maximize -e "bash -c 'nvim /home/user/rc.xml'" .. again .. this keybinding opens the rc.xml file with nvim, but not with the maximised gnome-terminal window as needed ... gnome-terminal --window --maximize -e "/bin/bash -c ' nvim /home/user/rc.xml; exit; exec /bin/bash -i'" .. again .. this keybinding opens the rc.xml file with nvim, but not with the maximised gnome-terminal window as needed ... /home/user/linux_config/script_vim/rc.xml.sh .. with the above script simply containing #!/bin/bash gnome-terminal --start-maximized -e \"bash -c 'nvim /home/user/rc.xml'\" I am not aware of any parameter within my .vimrc file that is stopping the terminal window opening maximised. Can anyone suggest how I can adjust my key binding to open this window maximised?
