Properties Rename at a shot - Help

Hi Friends

Just to introduce I am not an expert in programming. Just used to browse around and make some small events in autoplay. My question is.. Is there a way to change some string lines in multiple objects at same time ?

Ex: I have 5 different buttons. In their separted code, they all have a " specific and similar " name I would like to change. Ex - " command_alfa " ! This line, " command _alfa" is writen in all five buttons, inside their codes. I would like to change them all to " command_beta "! The only way I know to change them all is, opening every single button, one at a time , and changing the text I want to change! So, the question is, is there a way to change the text in all buttons at same time ? or change a " text , string " in all elements into the screen ( simillar texts of course ) at same time ?

many of my elements in the screen have strings like " , something_A , something_B ... " and I would like to change them all at one single shot! Possible ? Currently I am opening element by elemnt and chaging all them manualy !

I hope someone can help me !
