When you’re in Adobe InDesign and you have a text block that you have carefully set right-aligned tabs for using the tab bar, you’re somewhat stuck with the tab setting if you need to resize the frame. The tab setting stays where it is regardless of any width adjustments you make to the text frame. You can make it much easier on yourself simply by hitting Shift + Tab. This will automatically put the text after the tab to the far right point of the text frame regardless of the width of the text frame. This of course makes it much easier on you if you need to make that frame a bit thinner or wider.
