If you are using Microsoft Word, Ctrl-Shift-: (colon), followed by 'u'. However, most sites accept a 'v' in pinyin in place of the 'ü' - called 'u-umlaut' officially, but 'u with dots' is understood. For example 旅 could be written lǚ or lv3.

"lv"

I assume you want to know how to input the Chinese character 旅 using PINYIN-INPUT-METHODS. In this case, you just got to enter LV.

i want to now too normally i will type the full word ex: lu xing he lu you de lu
