Well, excuse me....it has been a bit frustrating to achieve what should be a relatively simple task I would think
If its so simple but you can't do it, don't get annoyed with others ...
That aside, one way to line up text and other items is to use frames. You see frames used extensively in some programs that convert scanned images to Word documents.
Text and images within frames can be positioned on the page as required.
But for a simple task like a line next to a word, draw a line using the drawing tools.
In Word 2003, right-click on a toolbar, and from the drop-down select 'Drawing'. This shows the drawing toolbar.
From the Drawing toolbar select the line icon (between Autoshapes and Arrows)
Ignore the 'Create your Drawing here' box and draw a line on the page.
Drag it into position.
Click 'Draw' on the Drawing toolbar and use nudge options to make small adjustments.
You will probably need to deselect 'Snap objects to grid' (Draw - Grid Icon - dialog box - clear check box)
Right click the line and select 'Order'
Select the 'behind text' option - then you can get it right against the text without affecting the text.
The line length can be adjusted by dragging or by right-clicking and selecting 'Format Auto Shape'
This option also allows line thickness to be selected.
Once your line is very close to the text (including spaces), it can be hard to select it, because the text gets selected instead. In this case use the 'Select Objects' icon on the Drawing toolbar (next to the Draw button).
Click the 'Select objects' icon again to return to normal mouse/cursor function.
