Effect: TC is able to cd to regular paths, also it allows to jump to paths via editing path in a path panels, but paths with envvars don't work, e.g. cd %TEMP% in a command line simply does nothing, also if I paste %TEMP% to path panel, TC shows auto-complete but Enter does nothing.
The parameter %A tells TC to pass the command line to the command exactly as entered. It depends on the called program or function whether it supports env vars or not.
