How to show two or more editors at the same time?

Eclipse allows to show more than one code editor at the same time... so you can have 开发者_StackOverflow中文版something like this:

Can I do something like that using IntelliJ Idea?

There are two ways to do it:

1. Click the tab header, then split vertically/horizontally. (works prior to IDEA 10).

2. Just click the tab header and holding left mouse button move the tab out of the window (separate editor will open). (IDEA 10). (See Detachable tab editors section on the features page.)

When using the second option I find that global history (CTRL+ALT+arrows) is spammed. See bug IDEA-64656 Navigation (Back & Forward) works incorrectly in the case of splitted editors and it is finally fixed in the 103.190 EAP build

Right click on a tab with file name and select 'Split Vertically'/'Split horizontally'
