 So let's assume for a moment you want to add in an equation to Microsoft Word. Normally most people will go insert, they will find the equation object and then you will start messing around with scripts and trying to do X squared and so on and you'll be getting these from menu buttons and it takes a while to go through all of those things where you might want to insert these things. But you don't need to do that, you can actually do it much quicker if you learn to use a couple of the typing commands. So to insert an equation alt equals is the shortcut and if you want to do X squared, you can type in X, then the carrot symbol which is shift 6 on most keyboards to then spacebar and it automatically formats. And you can also put subscripts in as well by using an underscore, so usually that shift then the minus button on most keyboards as well. Type in I for instance and it formats it as a subscript. So if you want to do chemical structures you can do chemical structures very very easily like that, it will automatically format everything. Probably not the best option for doing chemical structures but they are there anyway. So let's say you want to insert a thermodynamics equation let's put alt equals and then you'd start inserting special characters in order to find a delta to make delta G. So if you need to do that you can just type in delta and it will format it as the uppercase delta. If you do it all in a lower case remember you've got to type them right and spell them correctly, you'll actually get the lowercase delta. So we can do delta G equals delta H minus T delta X. We can also do the other delta G equation if we do delta G equals minus RT log K which is another equation there. And you can get as fancy as you like with these once you know some of them. So there are various useful characters as well. You can do times for multiply, you can use backslash PM, all of these things are preceded by a backslash and then you just start typing what it is and normally if you come up here and you have a look at what the tooltip says you can do it. So say if you want the proportional symbol it's prop2 and it inserts that as well. And if you want to do things like fractions the forward slash will do it. So we can say type let's say type in an equilibrium constant. We want to do K underscore A equals and this is where setting a little bit up before you start typing helps. Open and close a bracket, open and close a bracket again, forward slash open and close a bracket and then space bar to set that. And up here I can do A, carat sign minus to make the conjugate base H, carat sign plus to make the acid and H, that's it. You can then start doing a lot more complicated things when you know most of the commands.
