Useful Shortcuts For Mac

Last updated: 28/05/17 Short cuts are combinations of keys that you can use to perform tasks with your keyboard.  Short cuts can save you a lot of time, so it is worth your time memorising them.  Nevertheless, there are lots that you can use, so I have listed a few that I find particularly useful.  These are my favourite short cuts for Mac (Yosemite). Safari and word processor short cuts Command + Z This will undo the last action.  This includes opening up an accidentally closed tab; you will have to use this short cut immediately, however. Command + A This will select all and can be used in many applications.

Spotlight: The Operators

Image
   If you do not already have Scratch or need extra help, please use the support page The operators manipulate data. You will notice that the blocks have different shapes.  Subsequently, some fit together into some blocks but not others.  Test it out and find out which blocks fit together The first four perform basic maths operations: add, subtract, multiply and divide where divide will give a decimal (the numbers entered in are floating point such as 6.0).  Remember the order of operations matters; furthermore, the rounded blocks will act as parentheses, so anything to be calculated first is anything in parenthesis. Example: (2+3+4) x5 = 45 2+3+ 4 x5 = 25 The next block will pick a random number between any two numbers that you enter. The inequality and equals signs < less than, for example 2 < 6 > Greater than, for example 45 > 20 = Equal, for example 3 = 3 The Boolean operators (named after Geor
