When using the default Terminal in 18.04, i'm getting weird behaviour.

  • Zoom out shortcut is Ctrl + - , ok that works.
  • Normal Size shortcut is Ctrl + 0, that works.
  • Zoom in shortcut is Ctrl + +, doesn't work for me.yet, when i do Ctrl+Shift++ it works. what gives?

Is this just me or is there something conflicting with this??

    zoom in keyboard shortcut: CTRL++ is equal to CTRL+SHIFT+=

  • My mistake was trying to use the + & - on my numeric keyboard which do nothing instead of the 'main' keyboard

You need the shift key because the primary key results in a = sign.

Just open any text editor and press the =/+ key. If you press it with shift that results in a + sign, otherwise you'll get a =.

Get used to it because commands are often case sensitive! Take Vi editor, for instance, a is a different command than A (shift+a)

    In all the years ive used a computer, I dont think i've realized this. The two keys next to 0 and backspace, look reversed. I always thouse minus was on top and underscore on the bottom, but I guess thats not the case clearly from typing them. however, if you open up chrome for example, and do Ctrl + =, it will zoom in like most applications do and yet it will show - and + to increase/decrease. Kinda bizare... Aug 12, 2018 at 16:02
