Analogously the commands 24, 25, and 26 are
used to switch to the <#189#>shapes<#189#> `sloped', `italic' and
`smallcaps', this time leaving <#190#>family<#190#>, <#191#>series<#191#>, and <#192#> size<#192#> alone.
In addition, we introduce the 27 command, in case
one wants to switch back to the `normal' <#193#>shape<#193#>. If font changes
are done only inside of groups this command is necessary only to
reset a shape in a footnote or a similar context to avoid the
problem mentioned above.
