Five weird keyboard shortcuts that doctors hate. Number four will blow your mind!
Add emoji to your tweets and emails quickly by holding ≈+ç and pressing the spacebar. This displays a panel with icons divided into categories. There are useful bullet points and greek symbols there too. You can drag this panel away from the window you’re working in to keep it open (in the current app only), giving you even quicker access to unusual characters when you need to type many. You can invert the colours on the screen with ≈+å+ç+8. This colour scheme can be more restful at night, when ambient light is lower. You need to enable this shortcut in System Preferences > Keyboard > Shortcuts > Accessibility > Invert Colors first though. Instead of manually dragging files to the trash, or ≈- clicking and selecting Move to Trash, you can simply select files and hit ç+∫ to trash them. Need to type an accent or another diacritical mark? Don’t bother trying to guess which modifier key combination will do the trick. Instead, just hold down whichever letter needs the mark and a pop-up with all the alternatives will appear. If your keyboard lacks a ∂ (Delete) key, press ƒ+∫ deletes characters to the right of the insertion point.
All the diacritical marks you need are just a long key press away at any moment.
