Their purpose is to change the action of another key to perform a different task. By themselves, or pressed together, they will do nothing. Alt+Shift+< Go to Tell me what you want to do and Smart Lookup (in Word 2016). Ctrl and Alt are what are known as modifier keys.

I just stumbled over the issue and also kept note in my blog ( Gnome Shell Quickfix Cheatsheet). The ribbon is the strip at the top of Word, organized by tabs.

These fixes are keyboard independent and I can confirm not doing so will have the hotkeys Ctrl+Alt+Shift+Up, Ctrl+Alt+Shift+Down, Ctrl+Alt+Up and Ctrl+Alt+Down not working in Phpstorm as the Gnome Shell blocks them. $ dconf write /org/gnome/desktop/wm/keybindings/switch-to-workspace-down '' Set the number of (now static) workspaces to one: $ dconf write /org/gnome/desktop/wm/preferences/num-workspaces 1ĭisable the up/down keyboard shortcuts which are blocking Phpstorm: $ dconf write /org/gnome/desktop/wm/keybindings/switch-to-workspace-up '' So for Gnome Shell, disable dynamic workspaces: $ dconf write /org/gnome/mutter/dynamic-workspaces false Even the keyboard shortcuts differ a bit to Phpstorm (in my case there was the shift modifier which was not part of the Gnome shell shortcut binding), the workspace up/down block the keybindings in Phpstorm.

For Gnome Shell, the workspaces stand in the way.

What does ctrl alt shift do
