TMs should be created with two-way indexing, meaning that we should always be able to use both F7 and SHIFT+F7 functions to perform global searches in Source and Target sections of TMs opened in TMS TM Maintenance for quick and convivial corrections.
In some instances we can manage by searching in the Source for corrections to be made in Target, but sometimes we're left with the basic CTRL+F function to find content in Target, which might be quite time consuming.
Not sure if double indexation do slow anything (servers, software or else) but I find it very useful to be able to use both F7 and SHIFT+F7 in TMS TM Maintenance.
Thanks
