The bottom of my (Chromium) window is off the bottom of the screen. If I move the window up, Unity maximises the window (which I do not want).

What key combination can I press to make the active window shorter (smaller)?

  • Have you tried to press ctrl-alt-keypad 8 several times? – Xiè Jìléi May 27 '11 at 2:08

Hold down Alt and press space.

Then press R on your keyboard. You can now use the arrows to resize the window.

    it shows the arrow key to resize, but window is not resized. Should I press then another key to apply the change? – alhelal Jun 8 '17 at 11:54

You can press Alt + F8 and your mouse pointer will automatically switch to a resizing pointer, which you can use to resize your window either with the mouse or using the arrow keys.

You can then click or press esc to stop and turn your normal pointer back on.

    Cool - though alt-F8 seems to only change window width – Robert Brown May 23 '11 at 14:08

    Alt F7 allow me to move the window around without it snapping onto the top bar. That would've worked for me too. – Robert Brown May 23 '11 at 14:09

    It depends how you move your mouse after pressing F8. Horizontally → width, vertically → height, diagonally → both. – htorque May 23 '11 at 14:10

I tend to use alt + middle-drag to resize windows.

It's not pure keyboard but it is useful in awkward situations (like this)

    That doesn't work for me but thanks anyway – Robert Brown May 24 '11 at 12:50
  • You need to try this ~near the edges of the window. – smhg Jan 12 '17 at 10:57

    This is exactly what I was looking for. Thank you from 6 years in the future :) – CornSmith May 22 '17 at 0:37

    It's alt + right-drag for me. – Plasty Grove Dec 15 '17 at 6:48

Right-click the title bar, select Resize and then control the window size with the mouse.

    That works for decorated windows, but not for undecorated ones. – James Waldby - jwpat7 Dec 18 '11 at 0:08

I find Alt + right-click + drag to be the most convenient way to do this.

As there is no mention of the shortcut using super key I will add it. This is complete keyboard shortcut, which has a super key(key with windows symbol). Just press super key + ctrl and then use arrow keys to resize the window. Arrow Up and Down keys maximize and minimize current window respectively.

Bonus Tip: Hold the super key and a short cut menu pops up with all possible short cuts.Tested on ubuntu 14.04 and works on 16.04 also.

    This answer is excellent. Just note that 'super' + 'ctrl' + 'down' minimises the window. – WillC Feb 7 '18 at 0:24

The combo is different in Ubuntu (Unity) and Kubuntu (KDE).

Ubuntu 16.04 defaults to Alt + middle mouse button and then drag with mouse.

Kubuntu with KDE 5.8 defaults to Alt + right mouse button and then drag with mouse.

Place mouse on one of the nine edges, and then drag in the direction you want to upsize or downsize.
