In addition to SHIFT + RIGHT CLICK the item to get the item to [link] into /World, you may also simply drag the item into the actual text box window and release the item while it is hoovering over that text box window and this will create a link in /World as well. I do this method when using the AH ... it's takes far more time to type "anfalas scroll of empowerment' then it does to simply drag 'n' drop.
Off-topic, but another good AH 'tip' is ... when searching for an item with multiple words in the name description, (if you don't drag 'n' drop) type only the last few chacracters of one word and the space and then only the first few characters of the next word. Example: rather than type 'Emerald Shard', you can simply type 'ald sha' ... or instead of 'Universal Solvent" you can type "al solv". Obviously this won't work for items like 'greater essence of ..." if you type "er ess" because you will get EVERY greater essence listed. But it is a nice little shortcut once you get the hang of it ><
