I am using an Android device that runs Android 4.0.4 but without any touch screen (display on a normal TV). So I connect a wireless PC keyboard with touchpad to control the Android system. I could basically use this Android device.
However, when I come to the Android default browser, I could, for example, scroll down by pressing "space" in keyboard, but I could not zoom in a webpage using keyboard shortcut key. I know that "MENU + i" key could zoom in a page, but it seems that a normal PC keyboard does not have a "MENU" key. In addition, the touchpad seems does not support multi-touch for me to zoom using touch gesture.
The Android device's setting has disabled the software "zoom button" in the default browser. So I find no way to zoom webpages in such situation.
Is there any way that I could zoom webpages using the PC keyboard with touchpad ? Or could I enable the software "zoom button"?
