How to make objects appear when I want to see without clicking 'Disable/ object in render' For example, I want to make object appear from keyframe number 100 to keyframe number 200. And I don't want to see that object on 3D viewport and in render too. I already know the way clicking 'disable object in render' in Outliner menu. But that doesn't work on 3D viewport, so I want to know other way.
Keyframes can be added for the visibility settings. Select the object and open the Object tab. In the Visibility panel you can adjust the settings and insert a keyframe either through the context menu or by pressing I.

For your specific problem, you could insert a keyframe at frame 0 with Show in Viewports and Show in Render disabled, then a keyframe at frame 100 with Show in Viewports and Show in Render enabled, followed by a keyframe at 201 with both disabled again.
