Access the RemDim tool by pressing and holding the [TOOLS] button (or [T] on the QWERTY keyboard) then select [S10] (you may need to select <more> if RemDim is not visible):

If RemDim was your last Tool, then just pressing and releasing [TOOLS] will perform a RemDim.
If fixture 1 is at 0%, typing [1] [REMDIM] will take fixture 1 to 100% (or the Full level as set in Show Options) and all other fixtures above 0% in the current cue list to 0%. The second press of [REMDIM] will take all fixtures, regardless of playback, to 0%.
If fixture 1 is at some level set by the current cue list, typing [1] [REMDIM] will set all other fixtures above 0% in the current cue list to 0% and leave fixture 1 at its current level.
The syntax [1] [@] [5] [REMDIM] takes fixture 1 to 50% and others in the current cue list above 0% to 0%. Again, the second press of [REMDIM] will take all fixtures to 0%.
Typing [REMDIM] by itself takes all fixtures in the current cue list above 0% to 0%.
