How to open keybindings.json in VSCode

You can also open the keybindings.json file from the Command Palette (Ctrl+Shift+P) with the Preferences: Open Keyboard Shortcuts (JSON) command.

Here's my file for toggling the console:

// Place your key bindings in this file to override the defaults
[
{
"key": "shift+space",
"command": "workbench.action.toggleMaximizedPanel",
// "command": "workbench.action.toggleEditorVisibility" either one
"when": "!terminalFocus"
},
]
