The embodiments herein describe a mode of applications on the portable electronic device that improves single-handed operation of the devices. For example, the embodiments herein describe an ergonomic mode of an application that displays the graphical user interface (GUI) of the application in a bottom area of the display screen of the electronic device to allow the user to more easily interact with objects. The embodiments herein also describe an ergonomic mode of a keyboard displayed on the display screen of the portable electronic device. During the ergonomic mode of the keyboard, the keyboard is shifted towards a vertical edge of the display screen to allow a user to more easily reach keys of the keyboard that were previously unreachable without the user switching to two handed operation of the device or repositioning the electronic device in the user's hand.
