Do you know how to parse string which are wrapped in a keywords?

I'm trying to parse an application with Poedit. Most of my translation use a translate() method but in some views file (.phtml) I use a special keyword such as My string

Do you know could I specify to poedit ?

Thank you

Edit:

I know how to add keyword such translate, setLabel, e开发者_StackOverflow社区tc... but they are all methods. I need to add something like %s and poedit will know that the string to translate is %s which wrapped around tag element

After opening a *.po file, got Catalog > Settings > Keywords to add your keyword.
