What do you need this counter for? With <#165#>g<#165#> or the `<#166#>.<#166#>' on the number keypad you jump to the page that the PJC indicates. Thus, by entering <#167#>c 1 5 g<#167#> you jump to page 15. After that, the counter is set back to zero automatically.
On top of this, it is also used with the other keys for changing a page. With <#168#>3 RETURN<#168#> you jump forward three pages with <#169#>7 -<#169#> seven pages back.
With the help of this counter, the number keypad and cursor keys are completely sufficient, to move swiftly in a DVI file.
The keys <#170#>g<#170#> and <#171#>.<#171#> too can be switched temporarily to the use of the physical page numbers by pressing (and holding) the <#172#>Ctrl<#172#> key. Thus, with <#173#>1 5 Ctrl-g<#173#> you get to the 15th page within the DVI file. This can have without problem one of fifteen different (logical) page numbers.
