 Rhaen, yna'r tiff gŵith cymysgau i'r cymysgau. Rwy'n amlwg o'r cwmpanol yn ymdrydd. Rwy'n rwy'n meddwl i'r ddweud o'r twym ni. A ddim gŵr ddweud o'r cwmpanol, o'r ddweud i'r cymysgau i'r cymysgau. Rwy'n meddwl i'r cwmpu'r ddweud i'r cwmpanol a'r cymysgau i'r ddweud i'r ddweud i'r gweith. cyntedd gwneud'r ddadod, ac yn bwysig y gwneud o gympound 1. Fe bwyng y caelwyddo. A llydydd y dda'r un cymdeithas, Ac mae gennym eich cymdeithledd cympound 1 o wnaeth gwych. Ond yn ddim tu'r gwnaeth... Mae'r ddobl yn gyda thwy o'r ddaeth, mae'n ddyfaktyn eich ddwy. Felly yw'r un gweithio, eich ddwy'r dda'i, ac mae'n cymdwyr yw'r cympound 1. ond now a now I need to read the number of this as two, which means I need to find this as compound two. Now you can do that manually and you've only got two or three in a lab report, maybe this will be quicker, but if you've got running into dozens of them, there are easier ways to do this. So what we're going to do is use the built-in captions. So under the references tab we're going to insert a caption and I'm going to create a new label called it doesn't really matter whether we're going to use it this way. We're going to use it in a slightly different way in a moment. So I'm going to OK that compound one and I'm just going to remove that. So once I've deleted that part that says compound, I've got one here and then I can go to references, cross reference, which is this number here and then here it is compound one. Honey label number and insert that right. That could be a little bit tricky. So now we've got that all set up. What I'm going to do is press control F9 to bring up a new field. So this might be new for people because what these numbers are, they are a sequence field and we can do that by typing SEQ and then a space and I want to tell what sequence I'm dealing with. So I'm going to type in the world compound. Great. Once I've done that, this is the field that actually generates it. I'm going to press F9 and there we have compound one. This is the exact same route as inserting caption, but you might find it a little bit easier rather than clicking around. Now if I right click and update these fields here, they have updated to number two. Again, I can do references, cross reference. Alternatively, I can right click, cross reference and add to quick access toolbar and that appears all the way up here in the top left. If I press alt, it immediately flags up a load of different numbers and options for me to insert things in. So if I press alt and then type six, I get to my cross reference. So I can write compound one or reacts with H2 to form alt six compound two and this will keep track of your number. So if we want to replace that control X, put that up there. I can update all of these fields and it will automatically update everything. So if you do have ChemDraw objects in and you press control A, the ChemDraw thing does override the update field thing. So you may want to paste images once you've done with them, but at least if they are ChemDraw objects, you can edit them afterwards. That is one way of keeping track of your compounds. If you're writing a large dissertation, it usually helps to have these on a big page at the very beginning. So you can fold it out. Certainly done in a few of the big PhD thesis do that and it makes it reading easier. So if you build that first, you can then start referencing your compounds.
