How to type 'ந்'?
That is very simple. You have to use either 'n' or 'nh'. As you keep typing continuously, 'n' at the starting of words will always give 'ந்' only. But, if you move the cursor around and start typing at some random point of your already-typed text, then 'n' may give 'ன்' only. In such cases, you have to use 'nh'. Of course, you can opt to always use 'nh' itself at all times (at starting or middle of words) so that you always get ந். It is your choice eventually, based on your convenience.

Tips - Typing ஹ் in middle of words
There are 3 ways to type ஹ் in the middle of words when the 'ஹ்' has to be generated after a 'mey'. i.e. after b, f, g, j, k, l, m, r, v, w, x, y, ch, sh, dh, th, etc.

For e.g. say, you wish to type நரசிம்ஹன் or கமல்ஹாசன்.

1. Type it straightaway as 'narasimhan' or 'kamalhaasan'. For this to work correctly, you have to ensure that the option "Exclude 'h' in words like Bhairavar" is kept UN-ticked. You can find this option in Azhagi+ if you click the 'Settings->Preferences' menu item and then click on 'TAMIL' in the left pane.

2. In case you wish# to keep the abovementioned option always ticked#, then to generate நரசிம்ஹன் or கமல்ஹாசன்
Either:
type narasimHan or kamalHaasan(i.e. use 'H' to generate 'ஹ்')
Or:
type narasimhhan or kamalhhaasan (i.e. type 'h' twice to generate 'ஹ்').

(#) please note that if you keep the abovementioned option ticked, you can easily type names like bhairavar, khushboo, raghu, prabhu, jhaansi, etc. just as you are used to write them (with the silent 'h' in them) rather than forced to write them as bairavar, kushboo, ragu, prabu, jaansi, etc.

A Recap and more SPECIAL CASES
What follows below is a recap of the salient key mappings and also various "special cases". Please read them without fail so that you can use Azhagi+ at it's EASIEST best, availing all the FLEXIBLE key mappings:

aum / Aum / OM
ௐ
.
.
lx, rx, nx, lxx, rxx, nxx, llx, rrx, nnx, sx, shx, sxx (only in 'Azhagi' android app)
ள், ற், ண், ள்ள், ற்ற், ண்ண், ள்ள், ற்ற், ண்ண், ஸ், ஶ், ऽ (avagraha)

e.g. kaalxai, irxaivan, kanx, ulxxam, karxxu, kanxxan, ullxam, karrxu, kannxan, sxaagaram, shxivan = காளை, இறைவன், கண், உள்ளம், கற்று, கண்ணன், உள்ளம், கற்று, கண்ணன், ஸாகரம், ஶிவன்

Note: The above facility is a unique feature amongst Indic apps, as of now. This facility allows you to use the 'x' modifier feature of Azhagi and transliterate some oft-used characters without using the shift key.

k / g / c / kh / gh / K / C / G
க்
.
.
x / ksh
க்ஷ்
.
.
csh / Ksh

e.g. elecshan = எலெக்‌ஷன், dairacshan = டைரக்‌ஷன், aKshayaa = அக்‌ஷயா
.
.
S / s
ஸ்

Note: swaami, namaskaaram, viswam = ஸ்வாமி, நமஸ்காரம், விஸ்வம்

As you can notice, there was no need to type Swaami, namaSkaaram, viSwam. i.e. there was no need to use 'S' (capital 's'). In other words, whenever a mey follows 's' (ச்), Azhagi will automatically convert s (ச்) to S (ஸ்).

http://azhagi.com/az-tamil-modern.html - this  page contains all the above information and more, including a consolidated table showing the key mappings for all the Tamil letters (has all 'consonant+vowel' combinations). So, please do visit and see. 

An alternate Tamil transliteration scheme (Alt+4 mode)
Azhagi+ helps you type in an alternate Tamil transliteration scheme too - wherein the key mappings are such that  'ee' is mapped to 'ஏ', 'oo' is mapped to 'ஓ', 'w' is mapped to 'ந்', etc. 

This scheme has been provided to help users who are already accustomed to type using such a scheme. 

To type using this scheme, you have to press Alt+4 hotkey instead of Alt+3. 

And, to know the key mappings for this alternate Tamil transliteration scheme, just click on "Tamil (Alt+4 mode)" in the adjacent list box. You can view the same key mappings online too at http://azhagi.com/xmls/udph/AzhagiPlus-Tamil-Unicode-UserDefinedPhonetics1.xml
