Preserve Bold & Italics while cut paste

@Ranjan – instead of "cut" and "paste" you could use the move() method of the texts object of your source text frame or your selection, if text ist selected.

See screenshot:

See my snippet with annotations:

//In InDesign CS5.5 you can use the click order in the UI to determine 
//what selected object is [0] and [1] etc.
//if you select two objects, [0] is the first one, [1] the second one.
//So to move formatted text from the left to the right text frame
//first click on the left text frame, hold shift and click on the right one
//before executing this code:
var sel = app.selection;
sel[0].texts[0].move(LocationOptions.AFTER,sel[1].insertionPoints[0]);

More generally spoken:

sourceTextFrame.texts[0].move(LocationOptions.AFTER,targetTextFrame.insertionPoints[0]);

You could also move selected text to another insertionPoint:

app.selection[0].texts[0].move(LocationOptions.AFTER,targetTextFrame.insertionPoints[0]);

You need to set Clipboard Handling in the preferences. You can do that in the interface (Edit > Preferences > Clipboard Handling), and you can probably set it in your script, too.
