這是什麼
當使用者在表格或樹狀清單（tree）中輸入一個項目的名稱，即直接跳選該項目。
何時使用
當介面使用可捲動清單、表格、下拉式選單、複式盒（combo box）或者樹狀清單
來表現一長串資料項目時。這些項目通常已經排序，如果不是依字母順序就是依數
字順序。使用者想要快速且精確地選擇某個特定的項目，並且傾向使用鍵盤操作。
這個模式常常使用在「檔案尋找」、長清單，以及選取國家或州的下拉式選單。也
可用在數字上 — 像是年份或金額；甚至可用在日曆時間，像是選擇月份或一週中
的某一天。
為何使用
人類不擅長掃視長串的文字或數字並從中找出特定項目；但電腦擅長。讓電腦為我
們服務吧！
使用此項技巧的另一個好處，就是使用者的手可以保持在鍵盤上。當使用者在表單
或對話框中移動時，只需要鍵入所需項目的前幾個字元，就可以輕易從清單中選出
想要的項目 — 系統會為使用者挑出項目，人們就可以繼續做後面的事 — 使用者或
許會覺得這樣還不錯。不需要捲動清單、不需要滑鼠點按，使用者的手可以一直放
在鍵盤上，根本不需要移到滑鼠上。
原理作法
當使用者輸入所尋找項目的第一個字母或數字時，就會直接跳到第一個符合使用者
鍵入字元的項目：清單會自動捲動，顯示符合的項目，並加以選取。
