Jeeehah!
What a quality of life improvement for smaller monitors :))
Go to  %APPDATA%  > HISE > editorData.json
and add any Shortcut Key under "LayoutData" in the Tab that you want to modify.
example:
...
"Content": [
  {
    "Type": "Tabs",
    "StyleData": {
    },
    "Font": "",
    "FontSize": 14.0,
    "LayoutData": {
      "ID": "ScriptEditorTabs",
      "Size": -0.5544946346088778,
      "Folded": -1,
      "Visible": true,
      "ForceFoldButton": 0,
      "ForceShowTitle": 0,
      "MinSize": -1,
      "FocusKeyPress": "F3",
      // "FoldKeyPress" : "ctrl + 1 
    },
...
Heres' mine :)
editorData.json
( F3 code editor, F4 Interface; ScriptWatchtable: ctrl-q, Componenlist ctrl-w, PropertyEditor ctrl-e )
