Keyboard shortcuts can be a great way to save small bits of time and to optimize the time you do spend on the computer. In this blog article, I will talk about the top ten most useful keyboard shortcuts for mac. In the spirit of the old OS X naming scheme, the editor is adding cat pictures.
#1 Hide

Hide completely hides the program you are currently on. It doesn’t minimize it or close it, instead, it is hidden. To use hide just hit Command+H.
#2 Minimize

Minimize does what it says. It will minimize whatever program you are currently using. To use minimize hit Command+M.
#3 Spotlight

Spotlight allows you to instantly open up a search bar to check through all your files and applications, which can be extremely useful when looking for a file or application on the fly. To access spotlight hit Spacebar+Command
#4 Adjust Levels More Precisely

When you adjust volume and brightness on your mac you see 16 little rectangles that represent the brightness/volume level. You might think that there are only 16 levels of adjustability, that’s where this shortcut comes in. It allows you to get far more precise with your levels. Just hold down Option+Shift; then use the volume/brightness keys as you usually would.
#5 Switching to Last Used Program

Sometimes when multitasking it is useful to be able to switch between two applications quickly. To do so hold down Command+Tab.
#6 Switching Between Programs

Similar to #5 it can often be useful to move between programs that may not have been the last used. To do this hold down Command+Tab again, but keep holding Command down. Then use your arrow keys to move left and right
#7 Force Quit

Sometimes a program will freeze up or stop functioning and oftentimes the best way to fix it is to force quit it and then reopen it. Unfortunately sometimes the program can make it hard or impossible to do on screen, so it’s useful to know the keyboard shortcut. To force quit an application hit Option+Command+Escape. To normally quit a program, hit Command+Q.
#8 Taking a Screenshot

Taking a screenshot of your screen can often be very useful if you are having a technical problem as well as generally being a great way to show others things from your perspective. To take a Screenshot hit Command+Shift+3 or to capture only a certain area use Command+Shift+4
#9 Adding Emojis

If you ever felt like you needed more emojis this shortcut is for you. It allows you to open up the emoji window on your mac. Hold Command+Ctrl+Spacebar
#10 Open Preferences

Each Application has its own preferences that let you make the application work how you want; to access them quickly hit Command key and the , key at the same time.
