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)?

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?

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 Commented May 23, 2011 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. Commented May 23, 2011 at 14:09

    It depends how you move your mouse after pressing F8. Horizontally → width, vertically → height, diagonally → both.

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

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

  • You need to try this ~near the edges of the window.

    It's alt + right-drag for me. Commented Dec 15, 2017 at 6:48

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.

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. Commented Dec 18, 2011 at 0:08

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.

The resize window key combination for LXDE is:

Hold down Alt and press space.

Then press Z on your keyboard. You can now use the arrows to resize the window. (If you have not pressed Alt-space this session, there might be a short delay of about half a second.)

(Pressing R will Roll Up/Down [minimise] the window.)

Click the mouse or press Esc to regain normal control of your keyboard.

Resize a window by dragging the edges or corner of the window. Hold down Shift while resizing to snap the window to the edges of the screen and other windows. Move or resize a window using only the keyboard. Press Alt + F7 to move a window or Alt + F8 to resize.

Kubuntu 22.04 / KDE Plasma 5.24.7

I added a second monitor and had a properties window become zero width. Nothing to grab or size.

  • Alt+Space was mapped to KRunner, and
  • Alt+F8 was not mapped.

Shortcuts — System Settings

Clearing the Alt+Space configuration had no effect.

Shortcuts — System Settings

  • Search for resize, or resize window then
  • + Add custom shortcut,
  • press and hold the Alt+F8 keys
  • √ Apply

Now I could Alt-Tab to the zero‑width properties window, press Alt+F8 to get the mouse sizing cursor.

While you are at it, you could search for Move Window and add Alt+F7 as its custom shortcut.
