There’s a lot of keyboard shortcuts available to a Mac user. As a primarily Windows user, I’ve found a few shortcuts that are extremely helpful as a programmer and may be useful to you too. If you’re interested in the full list here’s a list of hundreds of them.
Command + Tab – Move forward to the next most recently used application in a list of open applications. My most used shortcut. This also exists in Windows, but a lot of users aren’t aware of this shortcut.
Command + W – Close the frontmost window
Command + Spacebar – Access Spotlight for searching the web, iCloud and your local files
Shortcuts for screen captures
Command + Shift + 3 – Capture the screen to a file
Command + Shift + Control + 3 – Capture the screen to the Clipboard
Command + Shift + 4 – Capture a selection to a file
Command + Shift + Control + 4 – Capture a selection to the Clipboard. My most used shortcut when I just need to capture a certain portion of the screen and don’t want to save the file. Happens a lot.

Control + F - Move one character forward.
