Currently I am working on creating interlinear texts for French, the first text (Le Colonel Chabert) will show how Tachufind can really shine when it comes to learning grammar . . . it is set up to show both the Imperfect and Conditional forms as colored in the text, with the key at the top. This works best if you have actually loaded it into Tachufind, and have run the search-color-replace function (you can find more information on this in the tutorials) because then, no matter where you are in the text, you can just hover your mouse over the matching color box and get the same information. Incidentally, I am including a zip file of the French grammar searches (for Tachufind) I have created, after downloading, you will place them on your windows drive (C:\ProgramData\Tachufind) in the Tachufind folder, and then you should be able to load them in Tachufind. Be advised that the color searches may not necessarily color the whole part of the tense as you would see it in the grammar charts you will find in French books, which would be much more difficult to do, but what it does is select the distinguishing parts of the grammar, so you learn the differences between tenses, creating grammar searches takes practice, and French is especially challenging in that regard.

Note that all of these will use a translation provided by google translate, but have a dictionary at the bottom. In Tachufind, if you use the Find From End button, you can find the definition readily, and after you have found and read it, you can click the Return button which will return you to the point you left off (as long as you clicked you mouse in the text at the point you wanted to return to. Otherwise, you can usually repeat clicking the Find From Start or Find From End button to get back the the same word you looked up.)

I have added Text-To-Speech capability to Tachufind. You will need to install the language and the accompanying voice for Windows 10
if you do not have it. Normally if you have added a language, it will work unless you excluded the voice when you downloaded it.
When you load Tachufind, and click on the Text-To-Speech button, as shown in the image below, it will list whatever languages you have installed:
