Hi there! In this video we’re going to learn to  

2
00:00:09,680 --> 00:00:13,280
type in the chemical formulae in 
InDesign, so let’s get started.

3
00:00:14,320 --> 00:00:19,600
I already have some of the formulae typed in here, 
so I’m going to ensure that nothing is selected,  

4
00:00:20,240 --> 00:00:24,960
and then click the small plus button at the bottom 
of the character styles panel to create a style.  

5
00:00:26,000 --> 00:00:30,560
Double-click the new style, and rename 
it ‘superscript.’ So basically I need  

6
00:00:30,560 --> 00:00:34,960
the charges to be superscripted, which 
means, a little raised from the baseline.  

7
00:00:35,680 --> 00:00:39,520
Let’s go to ‘basic character formats’, 
and in the position dropdown list,  

8
00:00:39,520 --> 00:00:44,400
select either ‘superscript’, or ‘opentype 
superscript’, both should work just fine,  

9
00:00:44,400 --> 00:00:49,760
and hit okay. Similarly create another 
character style, and rename it ’subscript.’  

10
00:00:49,760 --> 00:00:55,520
We’ll need this for the valences. Now go to ‘basic 
character formats’ tab, and from the ‘position’  

11
00:00:55,520 --> 00:01:00,000
dropdown menu, select ‘subscript’, or 
‘opentype subscript’, and hit okay.

12
00:01:01,200 --> 00:01:06,240
Time to move on to paragraph styles, so click the 
small plus button at the bottom of the paragraph  

13
00:01:06,240 --> 00:01:12,240
styles panel, and then double-click the new style, 
and rename it, should you want to, I’ll keep it  

14
00:01:12,240 --> 00:01:18,080
as it is. Let’s click the ‘GREP style’ tab on 
the left, and then click ‘new grep style.’ From  

15
00:01:18,080 --> 00:01:23,120
the ‘apply style’ dropdown, select ‘superscript’ 
character style that we created a few moments ago.  

16
00:01:23,760 --> 00:01:29,360
Click the ‘to text’ option, and type in these 
symbols, without any spaces: \(\d*(\-|\+)\)

17
00:01:29,360 --> 00:01:34,400
That’s backslash, then open parenthesis, 
then another backslash, then the letter d,  

18
00:01:35,040 --> 00:01:39,840
then the asterisk sign, then another 
open parenthesis, then a backslash,  

19
00:01:40,880 --> 00:01:46,960
then a hyphen, then pipe, then 
another backslash, then a plus sign,  

20
00:01:47,760 --> 00:01:53,840
then close parenthesis, then a 
backslash, and finally close parenthesis.

21
00:01:53,840 --> 00:01:57,920
You don’t have to remember that, that’s why 
I just copied and pasted here, because even  

22
00:01:57,920 --> 00:02:03,360
I don’t remember that. So once you’ve fed the code 
in, click ‘new grep style’ to create another one.  

23
00:02:04,400 --> 00:02:07,760
From the ‘apply style’ dropdown, 
select ‘subscript’ character style  

24
00:02:07,760 --> 00:02:13,680
that we created a few moments ago. Click the 
‘to text’ option, and type in these symbols,  

25
00:02:13,680 --> 00:02:15,840
without any spaces:
(?<=[A-Z]|[a-z])\d{1,2}

26
00:02:15,840 --> 00:02:23,760
That’s open parenthesis, then a question mark, 
then less than sign, then equal sign, then open  

27
00:02:23,760 --> 00:02:33,360
bracket, then a capital A, then a hyphen, then 
a capital Z, then closed bracket, then pipe,  

28
00:02:34,320 --> 00:02:41,280
then open bracket, then a lower case ‘a’, 
then a hyphen, then a lower case ‘z’,  

29
00:02:42,000 --> 00:02:48,720
then closed bracket, then close parenthesis, 
then a backslash, then the letter d,  

30
00:02:49,760 --> 00:02:58,640
then open brace, then 1, then a comma, 
then 2, and finally, close brace.

31
00:02:59,520 --> 00:03:03,600
Like I mentioned earlier, you don’t have to 
remember that, that’s why even I just copied, and  

32
00:03:03,600 --> 00:03:10,240
pasted here, because even I don’t remember that. 
So once you’ve fed the code in, click okay. Now  

33
00:03:10,240 --> 00:03:15,040
select the text box, and then click the paragraph 
style you’ve just created, and you’ve got yourself  

34
00:03:15,040 --> 00:03:21,040
the chemical formulae typed in InDesign. 
Let’s add some leading space, and we’re done.

35
00:03:22,240 --> 00:03:33,600
Alright guys! That’s all for now, I’m going to 
see you in the next one pretty soon. Good bye!
