If you enter «'C:\times» and than add a single «'» you get «'C:×'», if you undo this substitution, the undo also deletes the «'». If the input of a «'» and the following substitution were separated into two undo entries, one would be able to undo them separately, thus enabling one to just cancel the substitution.

Today I learned that the \ + name + space sequence for entering selected Unicode characters meant that some valid Smalltalk could not be entered. For instance: 'C:\' [space] (i.e. some reasonable Windows file path in a String literal, followed by a space character) "C:\" [space] (i.e. some reasonable Windows file path in a comment, followed by a space character) a \~ b (i.e. some weird but possible binary selector) `a copyWith: $\` (i.e. some backtick compile time constant ending with a backslash) If Luciano or anyone thinks they really need this, we can add a preference.
