Goodnight.  
I need other technical help (support).  
There are two conversion operations.  
But for a single letter, after the apostrophe, parentheses or cuotas  
One from lowercase to uppercase, for use... with singer names (%artist%).  
Another, from uppercase to lowercase, to use... with the name of the song (%title%).

example for up (before -\> after):

D' **a** mmare -\> D' **A** mare  
John' **m** ary -\> John' **M** ary  
John, ( **t** he) Legend -\> John, ( **T** he) Legend  
Paul, " **t** he" Man -\> Paul, " **T** he" Man

example for down (before -\> after)

Can' **T** -\> Can' **t**  
I' **M** -\> I'm

Thanks.

Treat these with an action of the type "Case Conversion" in which you add the characters that describe a word boundary for you. Do not include the apostrophe.

The other cases like

> [@JoaoBC](#):
>
> D' **a** mmare -\> D' **A** mare

I see as a an upper case letter follwed by the apostrophe and 2 lowercase letters.  
Try  
`$regexp(%artist%,(\u)''(\l[a-z]),$1''\u$2)`  
I cannot think of anythig decent for

> [@JoaoBC](#):
>
> John' **m** ary -\> John' **M** ary

(is that a real case?)

Good morning.

I used the sequence  
Menu -\> Actions -\> Actions -\> New -\> (group name) "Capitalisar"  
-\> (new window) -\> New -\> mixed case -  
For each of the signs.  
|However, only the last one works.  
The configuration file looks like this:  
_capitalizar.mta_

**[#0]**  
**T=1**  
**F=\_ALL**  
**1=1**  
**2="**

**[#1]**  
**T=1**  
**F=\_ALL**  
**1=1**  
**2=[**

**[#2]**  
**T=1**  
**F=\_ALL**  
**1=1**  
**2=(**

**[#3]**  
**T=1**  
**F=\_ALL**  
**1=1**  
**2={**

E o arquivo _capitalizar.mtg_

**selection=Case conversion\u000b0\u000bCD-R\u000b0\u000bStandard\u000b0\u000bCapitalizar\u000b1\u000b**

Do not create a separate action for each character that describes a word boundary but just 1.  
In that action enter a list of characters like  
`"(.: /`  
Otherwise you execute the action several times and each time only the single character is taken and that may reverse the conversion of the previous actions.

And just as @lyricslover pointed out: it is also no good idea to apply such an action to \_ALL. There may be unwanted side effects.

Please not also, that there are a number of artists who like their names with strange cases like  
t.A.T.u.  
2Inventions  
2Pac  
a l l i e  
A\*Teens  
ZZ Top  
AC/DC  
a-ha

and many more
