Ubuntu Eclipse Command Completion failure (reprint)

My eclipse 3.4, downloaded from the IBM Web site to use after the decompression. The automatic completion function (ALT +/) is found to be invalid.

The solution:

1. (Eclipse) window-----preferences-----or enter keys directly in the preferences, which corresponds to the shortcut for Word completion (ALT + /) Remove (select the shortcut key line that needs to be changed, delete it with backspace in the binding).

2. Find "Content Assist", press Alt in the binding, and then press/(ALT +/).

Sometimes, after we modify it, the Eclipse shortcut key doesn't work. This may be a conflict with the Ubuntu system shortcut keys. We need to erase the shortcut keys for Alt +/in Ubuntu.

The solution:

1, (Ubuntu) system----perferences---Keybord shortcuts, find ALT +/corresponding column, press BACKSPACE, shiny its status is disabled.
