Few weeks ago Ubuntu 11.04 (Natty Narwhall) has released with new environment (unity desktop) which actually make some ubuntu users feel strange with ubuntu 11.04 new interface. Indeed some part of desktop looks different than previous but not entirely bad, I promise that you'll fall in love `soon` when you know more.

Here are unity keyboard shortcut and mouse trick on Ubuntu 11.04 Natty Narwhall, hope this will help you to feels comfort and familliar with this new environment.

Launcher

  • Hold Super - Invoke the Launcher.
  • Hold Super, then 1 or 2 or 3 and so on until 0 - Open or focus an application. The number corresponds to the location of the icon on the launcher from top to bottom.
    • Adding Shift will open a new instance of the application if it's already open.
    • Holding the key is also useful when you want to get to the Launcher but do not want to invoke the Dash.
  • Super-T - Open the rubbish bin/trash can.
  • Alt-F1 - Put keyboard focus on the Launcher, use arrow keys to navigate, Enter launches an application, Right arrow exposes the quicklists if an application has them.
  • Ctrl-Alt-T - Launch a terminal window.
  • Super-A - Open Applications place
  • Super-F - Open Files & Folders place

Dash

  • Tap Super - Opens the Dash
  • Alt-F2 - Invoke the Dash in a "special mode" to run a command. Typing in a Folder Name will find that folder in Nautilus, you can also use ~ as a shortcut in the field.
  • The Dash opens with focus on the search box to find applications and files. Using the arrow keys will navigate the results, use Enter to launch.

Panel

  • F10 - Open the first menu on the panel, use the arrows keys to "scrub" across the menus. (There is no shortcut for the session menu, so hitting F10 and left arrow is a quick way to get there)
    • Press Esc to close the menus without choosing anything.

Window Management

  • Super-W - Spread mode, zoom out on all windows in all workspaces.
  • Super-D - Minimize all windows; hitting it again restores them.

  • Ctrl-Alt-Numpad 8 - Place window in top half of screen.
  • Ctrl-Alt-Numpad 9 - Place window in top right corner of screen.
  • Ctrl-Alt-Numpad 4 - Place window on the left side of the screen.

  • Ctrl-Alt-Numpad 2 - Place window in the bottom half of the screen.
  • Ctrl-Alt-Numpad 3 - Place window in the bottom right corner of the screen.
  • Ctrl-Alt-Numpad 0 - Maximize window.

Mouse Tricks

Launcher

  • Clicking and holding an icon and then dragging it around will allow you to reorder it on the launcher. You can also drag it off to the right of the launcher to move it around. Note that you need to make an explicit movement to the right to move the icon off the launcher before you can move it around.
  • Dragging and Dropping an icon into the trash can will remove it from the Launcher. The program itself will remain installed and accessible through the dash.
  • Scrolling the mouse wheel while over the Launcher scrolls the icons if you have too many and need to move around quickly.

Window Management

  • Maximizing - Dragging a window to the top panel will maximize it.
  • Restore - There are two ways to restore, or unmaximize, the topmost maximized window of the current monitor for this workspace (not using the window controls)
    • Double clicking on the top panel (but not in the application's menu)
    • Dragging the top panel down.
  • Middle click on Maximize - Maximize Window Vertically.
  • Right click on Maximize - Maximize Window Horizontally
  • Focus the topmost maximized window of the current monitor for this workspace: Left click on the top panel (but not in the application's menu)
  • Cycle between maximized windows of the current monitor for this workspace: Middle click on the top panel (but not in the application's menu)
  • Tiling - Dragging a Window to the left/right border will auto tile it to that side of the screen.
  • Middle click on an application's launcher icon - Open a new instance of the application in a new window. If the application isn't running it will just open it normally.
  • Middle click on the top panel (but not the menu) - send the current window behind all other windows.
