SlickEdit 2012 (v17.0.3.0 64-bit)
In the tabs popup menu, there are sort order commands: Alphabetical, Last Opened, Last Viewed and Manual.
These do not exist as independent _commands that can be bound to keys.
Add the following to bufftabs.e:
_command void set_file_tab_sort_order_alpha(...) name_info(','VSARG2_CMDLINE|VSARG2_EDITORCTL){
set_file_tab_sort_order(FILETAB_ALPHABETICAL);
sticky_message('Tabs ordered alphabetically, A O V M');
}
_command void set_file_tab_sort_order_opened(...) name_info(','VSARG2_CMDLINE|VSARG2_EDITORCTL){
set_file_tab_sort_order(FILETAB_MOST_RECENTLY_OPENED);
sticky_message('Tabs ordered recently opened, A O V M');
}
_command void set_file_tab_sort_order_viewed(...) name_info(','VSARG2_CMDLINE|VSARG2_EDITORCTL){
set_file_tab_sort_order(FILETAB_MOST_RECENTLY_VIEWED);
sticky_message('Tabs ordered recently viewed, A O V M');
}
_command void set_file_tab_sort_order_manual(...) name_info(','VSARG2_CMDLINE|VSARG2_EDITORCTL){
set_file_tab_sort_order(FILETAB_MANUAL);
sticky_message('Tabs ordered manually, A O V M');
}
And bind to taste.
